“My fiery breath is very hot! Those spiked balls are certainly not!”
Cloudjin is a cloud genie that was sent by Baby Bowser to patrol the mountains of Yoshi's Island in the game Yoshi's Story. As such, a Baby Yoshi must fight him after collecting thirty fruits in Stage 3-3: Poochy and Nippy. He attacks by using large, spiked, iron balls and causes them to roll down slippery teeter-totters, and breathes fire at Yoshi. However, three shots in the stomach by a Yoshi Egg (while he is tangible) defeat Cloudjin, allowing Yoshi to continue. Cloudjin is one of the five bosses found in the game.
