From the Super Mario Wiki
A Borp is a purple bush-like enemy with pale yellow star-shaped flowers on its body that has only appeared in Mario & Luigi: Bowser's Inside Story. They are only encountered at Cavi Cape. Bowser can punch them for extra coins, but Mario and Luigi have to fight them. In battle, Borps will spit out yellow blobs at the Mario Bros. Their attacks can be countered by jumping. These enemies are usually encountered in a group consisting of three or more Borps.
