Circus Kong
Circus Kongs are giant Mini Donkey Kong toys that appear in Mario vs. Donkey Kong 2: March of the Minis, Mario vs. Donkey Kong: Minis March Again!, and Mario vs. Donkey Kong: Mini-Land Mayhem!. If any Mini Marios touch one, the Circus Kong will throw them up in the air. They will be thrown back and forth (up to two at a time), and any additional Mini Marios will be stunned if they touch one. However, Circus Kongs can stop juggling the Mini Marios if another Mini Mario uses a Hammer or Fire Flower to stun them temporarily. Another way for the mini toys to get out of a Circus Kong's manhandling is to form a line of Pink Blocks under the Mini Marios when they're in the air, or if it happens to land on a red grid.
Circus Kongs are non-lethal enemies, and can only hurt Mini Marios if they are thrown into something harmful.
