Items of all shapes and sizes

[Rosencrantz]

oh and also you need to round out the green gourd a bit more
(I have no idea what the hell it's called; it's the green pumpkin thing)
the top corners of it are pretty flat, and it would look much better if you rounded them a bit more


and you should totally come up with a flower design for the superball powerup (like in Mario Land; that is clearly different than a fireball powerup)
and the carrot powerup from ML2
and even perhaps a Yoshi egg
