Can you help me out? I tried making a miniature version of the SMW grinder as seen above, but i can't seem to fix the collision and sprite. It's supposed to behave like the normal SMW grinder except that it cannot go on rails(the black lines the platforms go on) and is able to ride on walls like the SMB2 sparky and SMW spike top. I'm perfectly fine if you redo the sprite just to make this NPC. Thanks.
In case you didn't know, this mini grinder is the size of a single block. That is about the same width and height of a Goomba.
