Baron von Zeppelin

Baron Von Zeppelins are Balloons from the Yoshi games that carry items or hazards. They carry Keys, Coins, Red Coins, Boxes, Grenades, Needlenoses, and even Shy Guys. 3 Baron Von Zeppelins carry boxes meaning you'll have to hit them with 3 Eggs to get the Box.

Trivia

 * For some reason in Yoshi's Island DS to get Baron Von Zeppelin in the Museum, you have to hit the ones carrying hazards as a pose to just any Baron Von Zeppelin.
