I love the big hairy monster guy. He might not have any arms but you just want to hug him, even tho he won't hug back. The Doctor guy who owns him however, HE is scary. With a grotesquely over-sized head and massive eyes he makes Stewie Griffin from Family Guy look normal.
There's always some insane reason for Bugs Bunny to wander into his castle and get involved in a chase and that's exactly what happens. However, in the end Bugs and the monster become pals and the evil doctor gets what he deserves.
It's been done before and this cartoon is only one version of this same old plot but it's still very funny as anything with Bugs Bunny is. Daffy is still my fave tho.
