Hush
S04E20 Alan Arkin
By mistake, Alan consumes Bunsen Honeydew's Jekyll-and-Hyde concoction, transforming into a wild beast. He wreaks havoc while the adorably charming Bun-Bun Brothers perform "Zip-A-Dee-Doo-Dah." Kermit manages to ensnare Alan in a net, reverting him back to his normal self. However, the chaos doesn’t end there, as Kermit decides to take a taste of the potion himself shortly after.
