Zeb Zoober appeared in a television show called “Mystery Bears” in the 70s. Here he is with Kelly, the smartest girl in the gang. They became friends on set. Originally Kelly was supposed to be taking a solo picture, when Zeb photobombed her. They ended up taking this adorable picture together.

Mystery Bears is obviously a spoof of Scooby Doo
and Kelly is a spoof of Velma XD

Zeb owned by Disney
Velma owned by Warner Bros (I think)
