Yoshi Egg Animations and Egg Throws

[Milotic]

Hey, so I am having a problem with getting Yoshi's egg to roll on certain textures when doing a side guard dodge. It goes into an egg and skids across the ground without rolling. Also, when throwing eggs on certain textures it sends out a repetitive blob of a part of its texture instead of an egg. I think the two issues are independent, but how do I fix them. The texture that is having the rolling problem is the Baby Yoshi texture from Paper Mario. I am not sure how to go about fixing it, as for whatever reason, the MotionEtc pac that came with Project M's Yoshi made the baby Yoshi the size of a regular one, so I overrode it with the one provided. Any help would be great, thanks!
