Red and green mushroom tiles + bouncy pink mushroom from Mario DS

First topic message reminder :

When the player jumps, he can pass through the tiles from below and stand on top them.

Yeah need to work on those tiles
(how did you do that)

Nothing difficult, really. I only replaced tiles who already had these properties, such as the SMB's clouds.

Hey i got a problem with the bouncy pink mushrooms, they work perfectly, but i can still see the spring (fully black) in the left edge of the mushroom, how can i stop this?
