Grand Shoe Goomba:
This can be defeated by a single stomp. However due to it's massive size has the ability to only perform small hops every so often. When a Grand Shoe Goomba is defeated by a stomp or other means of attack the Grand Kuribo Shoe splits into two Kuribo Shoes. ( A nifty way to avoid the hard-coded shoe problem)
Micro Shoe Goomba:
This can be defeated by a single stomp. It's tiny size makes it a difficult target though as it can make extremely high, frequent jumps, like a Para-Troopa. When it is defeated the Micro Kuribo Shoe cannot be ridden due to it's tiny size, however it can be picked up and thrown once like a Veggie, taking out any enemies it hits on the way. ( Avoided the hard-coded shoe problem again... FOR THE WIN!)
Remember to make this effective you MUST use Layers and Events!
