Do you remember those weird spikey ball enemies from Yoshi's Island, Now those things are in SMB1, SMB3 and SMW art styles.
It's also includes a pokey-like variant which is based off their scrapped appearance from Yoshi's New Island.
If there are any problems with these sprites then feel free to let me know and if you are using these sprites for your own works, then crediting me would be highly appreciated.
