Truth be told he worries about certain things too much for my liking.
Oh and I looked on the Ni Hao, Kai-lan wiki and saw that Rintoo and Tolee aren't exactly friends. Dude, I don't mean to steal from a Monday Night Football(ESPN) segment but C'MON MAN!
DUDE, I ONLY HAVE 4 ****ING SKILLS what do あなた want me to do with him. and こんにちは you! he worrys a lot. He's a lot like worry くま, クマ from Julius Jr.
in my opinion, if he wanted to battle me i'll just tell him to play DDR(Dance Dance Revolution) against me!!! and do I need to tell あなた that Rintoo and Tolee, Rivals? F*** No!
