Fosley is one of the Dantini Guardians in Castle Island. He is encountered in Fosley's Freaky Donut walking around the island holding a red balloon. Furious, Baron Dante transforms him, turning Fosley into a larger version of himself who is now holding three balloons in which he is able to fly in the air with. Fosley attacks by throwing crab/spider like bombs at Croc which immediately start to chase him. To damage Fosley, Croc must lure in one of the bombs onto a spring, which will then launch the bomb at Fosley. Fosley has three hit points.
His appearance is somewhat similar to a mountain goat. He is purple, has two large incisors and carries a red balloon. When he is transformed his size increases drastically and carries three large balloons (red, blue, green).
- Throws Crab Bombs at Croc
- Fosley is the only Guardian which can be defeated without the tail whip attack. (Secret Sentinel requires a tail attack on the 4 gongs)
- If you fall off the ledge after hitting Fosley 3 times, Croc may die or stop on the brick ledge. This is the only level that you can die after defeating a Guardian.
- He is the last Guardian you must defeat that isn't Baron Dante/Secret Sentinel (crystal form of).
