Rocko's Modern Life to say the least had a very interesting cast of characters, from the mild mannered wallaby Rocko, the gluttonous steer Heffer, to the egotistical turtle Filbert. The thing I loved most about these 3 is when Heffer and Filburt would argue and fight. There's just something downright hilarious about them getting each other's faces and brawling. XD. Another thing I loved about this show was the Bigheads, especially Ed. He was just such a loudmouth jerk that you loved to see him getting his just comeuppance. Bev was another I kinda liked, although I thought she was too flirtatious with other men while married.
I even enjoyed the character Dr. Hutchison. Although, I do wonder why she married Filburt. Kinda of a bizarre pairing I have to admit.
Anyway, this show was one of the better ones from the 90's.
