New Kids on the Block (1990)

The music band "New Kids On The Block" (aka NKOTB) are the kings of this show. In the opening and ending of each episode they appear as themselves (also as introducing), and just after they (as cartoons yet) live all kind of adventures traveling by the world and taking their music and dance to everybody, meanwhile their manager only thinks in the money. The trues troubles come when appears a weird character that harasses to the NKOTB to force to sing under his rules, using all kind of bad tricks that it be necessary to get NKOTB, but they don't leave that it happen.
