The Apple is a red-yellow fruit that appears in Cube Escape: The Lake.
Cube Escape: The Lake Edit
If the player fishes using the head of a shrimp, they will fish up a corpse, which later reveals itself to be a Corrupted Soul. If the corpse is cut with a knife, they player can pull an apple out of its back. When the Apple is placed onto the tree that grows from The Fish, along with a gem, a coin, a shell and an eye, it will create a pentagram that summons the Corrupted Soul again.
- As of Cube Escape: The Cave, The Apple is the only one of the five pentagram items to not make a reappearance in the Rusty Lake universe.
