Bobobo-bo Bo-bobo (2005)

Season 1: Episode 73

Now officially in the tournament, Bo-bobo's team head inside the first battleground on a mountain of arenas: a bottle stage where their opponent is an extremely powerful warrior who uses the abilities of skulls to fight and transform into "a powerful old lady". But with Bo-bobo, Don Patch and Jelly smashing his skull abilities with the power of Mother Nature, he is forced to turn into his true form: a samba-loving goofball who attempts to force the Wiggins to follow the power of the beat...until they beat the beat out of him!
