1) That is an absurdly cute Mario.
2) Yoshi would be an interesting mount in a Bomberman game... eat your enemies, expel them as eggs behind you, and they have to mash their way out.
3) The description is pretty great...
That mount sounds absurdly overpowered, even by bomberman standards. Egg followed by 2 bomb trap would be pretty much instant death. I guess if the egg time was tiny, or the egg shielded you from an explosion.
