MOSI is a remarkable little boy who lives in BELLE's magical dance studio. His exuberance and optimism fuels his love for dance and imaginary adventures.

When she is in BELLE’s studio, MOO is MOSI’s little, yellow cat who can’t meow. She can only moo! But when this pink bowed kitty jumps through BELLE’s dance mirror, MOO grows to MOSI's size…and magically can sing and dance!

If you cross The Magic School Bus’s inquisitive Ms. Frizzle and the wonderful Mary Poppins, add a dash of Fame’s Debbie Allen and Santa Claus’s big belly laugh, you get BELLE.
