Diddy Kong

Diddy Kong is Donkey Kong's nephew and primary sidekick in the Donkey Kong series. In SMG4, he appears in SMG4: Mario VS Donkey Kong where he is first seen carrying Bananas to DK's House. Mario had managed to sneak in and disguise himself as a Banana but Diddy saw him so Mario put the Banana costume on him and put him into view of the security guards who proceeded to pounce him as they thought he was a real Banana and Mario made his cleanish getaway.
