Naruto volume 17 Easter Egg - Mask Man Is Space Shaman.

Get your copy of N17 and locate the part where Naruto buys (or wins) an ANBU black op mask.
Look at the rows of masks on the wall.
Look closely and see.. A Chiaotzu mask!
And also a Tokagero Mask!

For Shonen Jump n00bs Chiaotzu is a tiny man in Dragonball Z and Tokagero is a Gecko bandit's ghost in Shaman King.
