Spikey (Super Mario Land 2: 6 Golden Coins)
From the Super Mario Wiki
A Spikey is a hedgehog-like enemy found in the game Super Mario Land 2: 6 Golden Coins. It can only be found in the first level of the Tree Zone, near the base of the giant tree. A Spikey's attack pattern consists in curling itself up into a ball, then dashing forward in an attempt to ram Mario. Despite having spikes, Spikeys can be defeated by jumping on their heads.
