The Udjat Eye's key sealed in rock

Verified against the spelunky.ai port v0.1.12 on 28 October 2026.

This page describes a secret.

The Udjat Eye comes from a locked chest on one of levels 2 to 4, and its key is one of that level's treasures, turned into the key. Nothing checks that the player can reach the treasure it picks, so the key can lie in a pocket of rock that no way leads into, sometimes with the chest, and the rock has to be broken open.

Bombs have opened a pocket of rock that holds a locked chest and its key. An Arrow Trap fires over the player as he drops in; he picks up the key, crawls under the low rock to the chest, opens it and puts on the Udjat Eye ^[1].

The level that makes the locked chest, level 2 one time in 3, level 3 one time in 2, or else level 4, until one is made ^[2], turns one of its treasures into the key, after the treasure is placed. Each treasure that isn't inside a block takes a roll of 1 in 8, for up to seven passes, and if none wins, the first one takes it:

        n = 1;
        while (n < 8 and global.Key == false)
        {
            with oTreasure
            {
                if (rand(1,8) <= 1 and not collision_point(x, y, oSolid, 0, 0) and global.Key == false)
                {
                    if (type == "Gold Bars") instance_create(x, y+4, oKey);
                    else instance_create(x, y, oKey);
                    global.Key = true;
                    instance_destroy();
                    break;
                }
            }
            n += 1;
        }

The only test is that the treasure isn't inside a block. A treasure can be anywhere in the level, so the key can sit in a pocket that no way leads into. The chest goes in a nook in the rock, or beside the exit ^[3], so it's sometimes in the same pocket. The pocket's rock is ordinary, so an explosion or the Mattock's hit breaks it open ^[4]. The chest opens only to the key the player holds ^[5], so the key has to be carried to it.

Look for the locked chest and its key on level 2, 3 or 4, and carry the key to the chest. Some levels seal the key in a pocket, which a bomb dropped or thrown at its wall opens. The replay of the clip makes level 2, frame 1456, with the chest and the key sealed together in a pocket beside the shaft that drops to the exit. A bomb thrown down the shaft blows out five bricks at its foot (2053), and one put down against its wall blows out six more (2221), opening the pocket. The player drops in, picks up the key (2308) and crawls it to the chest, which opens and drops the Udjat Eye (2349). He picks the Eye up and it goes on (2364) ^[6].

The spelunky.ai port reproduces it exactly: it's in docs/quirks.md's list of the 1.1 source's bugs ^[4], and the oracle's fingerprint of the replay pins the sealed pocket, the bombs and the opened chest. No option turns it off.
