Bobopatch

When Bo-bobo has difficulty with A-Block leader Tokoro Tennosuke, Don Patch transforms into a small candy that Bo-bobo eats, allowing the both of them to fuse and become Bobopatch.

Bobopatch has long green hair with a bit covering one eye, a golden tiara, blue armor and a long cape with long, poofy pants. It appears as though Bobopatch is drawn in much finer detail than most of the series' art
