Lemmy's Bouncy Ball

[Cognition]

I cannot seem to find this for the life of me. I am looking for just the bouncy ball I can add to a level. If someone has Lemmy too then even better. I just need the ball to bounce like a jumping goomba but also knock the player around like a bumper npc. Thanks in advance.

Edit: Just to clarify, I am looking for just the Luna code. I can make the graphics. I just need the behavior.
