Well they were in need of a new pet.
Broster is a farcical, twice-weekly (typically Tuesdays and Thursdays), single-panel comic series about a BROther and a siSTER created by Joe Mohr. Besides cartooning and writing and illustrating, Joe writes lyrics and poems for (and raps in) a rock band for kids called ROBOT+BIKE. The music and the messages are enjoyed by parents and kids alike. Check it out!
