Verified against the spelunky.ai port [v0.1.10](https://github.com/851-labs/spelunky/releases/tag/v0.1.10) on 27 October 2026. *For the orange frog that explodes, see [Fire Frog](https://spelunky.ai/wiki/fire-frog).* The Frog is a monster of the Jungle in Spelunky Classic that sits still until the player comes near, then leaps at him in long jumps, biting for 1 heart. ![A blue-green frog crouched on the ground, its throat pulsing](https://spelunky.ai/wiki/media/1f61a00df79ad623/sprites/sFrogLeft/anim%404x.png) | Frog | | | ---------- | ---------------------------------------------------------------------------------------- | | Health | 1 hit point[^1] | | Damage | 1 heart[^2] | | Speed | 3 pixels per step[^3] | | Behaviour | Sits still, then leaps at a nearby player[^4] | | Object | `oFrog` | | Found in | The Jungle | | Dropped by | [Fire Frog](https://spelunky.ai/wiki/fire-frog), [Olmec](https://spelunky.ai/wiki/olmec) | Level generation puts Frogs on blocks all over the Jungle, under water as well as on land. A Frog doesn't move until the player comes within 64 pixels; then it jumps at him again and again, each jump carrying it several blocks, and bites him if it lands on him. With 1 hit point, it dies to any damage, whether from the Whip, a stomp or a thrown Rock. ## Behaviour **Clip: Frog jump.** A frog leaps at the player as he walks toward it and lands on him, taking a heart. ([video](https://spelunky.ai/wiki/media/1f61a00df79ad623/clips/frog/jump/clip.mp4)) A Frog sits still until the player is within 64 pixels of it, counting from the edges of the two, and then croaks and starts jumping[^5]. Each jump starts from the ground at 2–4 pixels per step upward and 3 pixels per step (90 per second) across, toward the player, and it keeps that speed across until it lands[^6]. A wall it hits sends it back the other way at 1 pixel per step, and a ceiling stops it rising[^7][^8]. Gravity adds 0.2 pixels per step to its fall every step, which brings it down again about 20, 30 or 40 steps after a jump at 2, 3 or 4 upward, so a jump carries it about 60, 90 or 120 pixels across, four to seven blocks[^9]. In the clip, its first jump, at 3 upward, carries it 93 pixels and 23 high, clean over the player's head; its second lands on him[^10]. When it lands, it stops dead and rests for 10–40 steps (0.33–1.33 seconds); if the player is still in range when the rest is over, it jumps again, and if not, it sits where it landed[^11][^12]. It never walks: jumping is its only way of moving. Water doesn't trouble a Frog: its gravity in water is the same 0.2 as in air, so it jumps and falls there as it does on land, and there's no drowning in its code[^9][^13][^14]. Like most monsters, it only acts while it's on screen or just off it[^15]. ## Damage When the player touches a Frog without stomping it, he loses 1 heart, is knocked away from it, and blinks, invincible, for 30 steps (1 second)[^16]. This is the touch code most monsters share; the Frog has no attack of its own, and the clip above shows a jump landing on the player and taking him from four hearts to three. ## Defeating A Frog has 1 hit point, so any damage kills it[^17]: | Way | Damage | | | ------------------------------------------------------------------ | -------------------------------------------------------------------------- | ----- | | Whip | 1 hit point | [^18] | | Machete | 2 hit points | [^18] | | Stomp (landing on it), except while the player is swimming | 1, plus 1 for every 16 steps of falling; three times that with Spike Shoes | [^19] | | A thrown item moving faster than 2 pixels per step, such as a Rock | 1 | [^20] | | A Shotgun or Pistol bullet | 4 hit points | [^21] | | A Bomb's explosion | 30 hit points | [^22] | | A Spear Trap's spears | 2 | [^23] | | Falling onto Spikes | Kills it | [^24] | | Standing in Lava | Kills it | [^25] | | Lava over its head | Removes it | [^26] | | Ending up inside solid ground | Kills it | [^27] | Frogs killed count toward the player's kills, and the screen between levels draws a Frog icon for each[^28][^29]. One that Spikes, Lava or a Spear Trap killed doesn't count[^30][^31][^32]. ## Locations Level generation makes Frogs only in the Jungle, levels 5–8, on top of blocks with open space above them, outside the starting room and shops, and not on a graveyard level[^33][^34]: - **On land**, a 1 in 30 chance for each such block, once the rolls for a [Mantrap](https://spelunky.ai/wiki/mantrap), a [Caveman](https://spelunky.ai/wiki/caveman) and a [Fire Frog](https://spelunky.ai/wiki/fire-frog) have failed[^35]. - **Under water**, where the block has water above it, a 1 in 30 chance once the roll for a Fire Frog has failed[^36]. Frogs also come from: - **Fire Frogs.** A Fire Frog that lands in water turns into a Frog[^37]. - **[Olmec](https://spelunky.ai/wiki/olmec)'s yellow balls**, which turn into a [Bat](https://spelunky.ai/wiki/bat), [Spider](https://spelunky.ai/wiki/spider), [Snake](https://spelunky.ai/wiki/snake), Frog or Fire Frog when they hit the ground[^38]. - **Custom levels**, as the level editor's tile `f`[^39]. ## Tips - A Frog doesn't move until the player is within 64 pixels, so one can be left sitting by keeping that far away. - Each jump keeps its speed across until the Frog lands, so a player who steps aside while it's in the air is out of its way. - A Frog rests after every landing, which is the moment to whip it. ## Trivia - The Frog's code names a walking state and a drowned state, but nothing ever puts a Frog in either: it only sits, jumps and lands[^40]. - A commented-out line beside its range check would have woken it at 48 pixels rather than 64[^41]. ## FAQ ### How much damage does a Frog do in Spelunky Classic? 1 heart per touch. A Frog that lands on or bumps into the player costs him 1 heart, knocks him back and makes him invincible for 30 steps (1 second). ### How do you kill a Frog in Spelunky Classic? Hit it once with anything. A Frog has 1 hit point, so a Whip hit, a stomp, a thrown item, a bullet or a Bomb kills it. ### Where do Frogs live in Spelunky Classic? In the Jungle, the only area whose level generation makes them, sitting on blocks on land and under water. One of [Olmec](https://spelunky.ai/wiki/olmec)'s yellow balls can also turn into a Frog. ### What is the difference between a Frog and a Fire Frog in Spelunky Classic? They move the same way and both die to one hit, but a [Fire Frog](https://spelunky.ai/wiki/fire-frog)'s body explodes four seconds after it dies, and a Fire Frog that falls into water turns into an ordinary Frog. ## See also - **Damaged by:** Whip, Machete, Spikes, Stomping[^19], Throwing[^20], Shotgun[^21], Pistol[^21], Bomb[^22], Spear Trap[^23], Lava[^42] - **Related:** [Fire Frog](https://spelunky.ai/wiki/fire-frog) ## References [^1]: `objects/oFrog/create.gml:15` [^2]: `objects/oEnemy/collision_oCharacter.gml:25` [^3]: `objects/oFrog/step.gml:66` [^4]: `objects/oFrog/step.gml:40-78` [^5]: `objects/oFrog/step.gml:38-47` [^6]: `objects/oFrog/step.gml:58-78` [^7]: `objects/oFrog/step.gml:25-33` [^8]: `objects/oFrog/step.gml:85-86` [^9]: `objects/oFrog/create.gml:8-9` [^10]: Clip frog/jump [^11]: `objects/oFrog/step.gml:48-57` [^12]: `objects/oFrog/step.gml:40-47` [^13]: `objects/oEnemy/create.gml:18` [^14]: `objects/oEnemy/step.gml:34-55` [^15]: `objects/oFrog/step.gml:3-4` [^16]: `objects/oEnemy/collision_oCharacter.gml:14-25` [^17]: `objects/oFrog/step.gml:13-23` [^18]: `objects/oEnemy/collision_oWhip.gml:1` [^19]: `objects/oEnemy/collision_oCharacter.gml:6-10` [^20]: `objects/oItem/step.gml:256-348` [^21]: `objects/oBullet/collision_oEnemy.gml:16` [^22]: `objects/oExplosion/collision_oEnemy.gml:14` [^23]: `objects/oEnemy/step.gml:76-106` [^24]: `objects/oEnemy/step.gml:108-128` [^25]: `objects/oEnemy/step.gml:65-74` [^26]: `objects/oEnemy/step.gml:63` [^27]: `objects/oFrog/step.gml:11` [^28]: `objects/oFrog/step.gml:16-21` [^29]: `objects/oTransition/alarm_0.gml:173-178` [^30]: `objects/oEnemy/step.gml:68` [^31]: `objects/oEnemy/step.gml:101` [^32]: `objects/oEnemy/step.gml:120` [^33]: `scripts/scrInitLevel.gml:26` [^34]: `scripts/scrEntityGen.gml:262-296` [^35]: `scripts/scrEntityGen.gml:285-292` [^36]: `scripts/scrEntityGen.gml:294-295` [^37]: `objects/oEnemy/step.gml:44-49` [^38]: `objects/oYellowBall/step.gml:4-19` [^39]: `scripts/scrCreateTileObj.gml:156-159` [^40]: `objects/oFrog/create.gml:22-28` [^41]: `objects/oFrog/step.gml:45` [^42]: `objects/oEnemy/step.gml:63-74` ### Source code - `objects/oFrog/create.gml` - `objects/oFrog/step.gml` - `objects/oEnemy/create.gml` - `objects/oEnemy/step.gml` - `objects/oEnemy/collision_oCharacter.gml` - `objects/oEnemy/collision_oWhip.gml` - `scripts/scrEntityGen.gml` - `objects/oYellowBall/step.gml`
