So this is it! I am using this Goomba at my project, but when transfering it between folders, I accidentally deleted (with Shift+Del) the old folder with the "effect" files inside, so this custom Goomba turns into the normal SMB1 Goomba when got hit.
I don't remember where I've downloaded it. I've tried about 7 graphic packs here at SMBX forum, but no one had this Goomba inside.
Could someone that have this Goomba upload the complete folder of him (with the effect files inside) for me? Thanks!
