Link-age : Season 2 Episode 8

Hamsterviel re-evils some experiments and causes them to do chaos again, such as Link who binds Yuna and Penny together, and Baby-fier who transforms everybody else (apart from Stitch) into tiny babies. While Stitch takes care of the babies, Yuna and Penny must try and co-operate together to find the antidote to get everyone back to normal.
