This block is similar to the Cape Remover but also remove the feather in the Item Box and replace with a mushroom. If you are using this block, I highly recommend that you use patches that changes the itembox to not drop down from the middle of the screen because the player can use L/R scroll to make it drop on the other side of the block and cheat the level. The patches are: Bottom Status Bar and the Instant Item Box
Or place it directly on the level entrance.
-the return code is missing
version 3 updates:
Fix the problem that if *flying* cape mario touches this block, mario is still flying as super mario and is showing glitch graphic, this time, will cancel his flying as well.
