A sleepy Goomba that sits still until Mario gets close enough, after which is wakes up and tries chasing him. It'll fall back to sleep after Mario stays away from it for long enough, unless the extra bit is set.
I didn't bother making a carryable version though, so it instead just gets squished when jumped on.
(Rykon-V73): Very small change: Converted the sprite to .json and added SP3 to the .bin file. This is to know where the .bin file goes.
Update accepted. During moderation I removed Info.txt since it was unnecessary, and converted 2 sprite tables since that seemed to be all that was needed to make the sprite SA-1 compatible. I also removed the gif since one is already included, and gifs should not be placed in the description field.
