Acornia

Acornia is a legendary pokemon found near the gates of your hometown. It looks like a giant acorn with feet, and several spikes come out of it's back, in additon to several torches. It is a fire and grass type. Acornia is supposedley the child of Treecornia, who created him so that he may be planted and grown into another Treecornia. However, he was unable to do this due to the town being build, so when Treecornia died he settled in a cave and attacked all who draw near it.
