This may be from a nostalgic standpoint, but I like this show. I just love weird/quirky shows and I remember watching this a lot when I was younger. To all the hate reviews about this show, I do understand the show's flaws and get what you're coming from, but just remember at the end of the day, it's just a mindless kid's cartoon. There's nothing "adult-themed" about it other than animals wearing underwear. Hell, even some children's shows have adult humor sprinkled into them, (for example, TAWOG, Adventure Time, Spongebob, Arthur, etc.)
The reason why I gave it 4 stars is it does contain gross-out scenes and toilet humor that I'm not a big fan of... But other than that, it's a decent show and is certainly one of my favorites growing up. I'm still watching it till this day, LOL.
