Stumblebooms are Hoodlums which appear as hoodbooms on stilts. They throw explosive bottles at Rayman whilst balancing on stilts out of reach and sometimes over toxic bogs to make it harder for Rayman to hit them.
They wear red cloaks with a hole in the top of their heads and have explosive bottles strapped around their fronts. Rayman can either stand underneath them to lure bombs to destroy the stilts or use the Vortex power up to spin the stumbleboom off of his stilts where Rayman can then punch him. The first one is found in the clearleaf Forest and can be defeated with the green Orange-Washing Powder.
