Do you know that in the last normal Rock Star level ( the one where you enter in a UFO) a Kiki from KDL3 appears in the Background?
Bobo means 'silly' in portuguese, and maybe spanish. :b
I'm spanish, and you are right, bobo means silly/dumb. :3
Bobo always looked kinda silly to me anyway.
They are some of my favorite enemies! They are so cute!
