Mushuda = no smell
The mushuda commercials are selling fragrant smelling moth repelling agents for wardrobes.
They feature 2 bears. Kumao (with the high pitched voice) and Kumamaro (with the low voice). Kumamaro is Kumao's brother in law.
3 commercials featuring Licca Chan with the Mushuda bears:
Mushuda Bears in the zoo:
Kumao: Oh look, that is moth-eaten fur!
Polar Bear: Where?! Where?! (takes off his "head") no kidding, you're right!!
Kumamaro (polar bear): Kumao!!
