How to Ratatwang Your Panda is, to paraphrase Gumball, a bargain-bin mockbuster of Kung Fu Panda (which has a foreign mockbuster version of it called Little Panda Fighter), even though the title is a mix of Ratatouille (which has a foreign mockbuster version of it called Ratatoing), Kung Fu Panda, and How to Train Your Dragon.The tune Banana Joe whistles is similar to the 'Twisted Nerve' music in Kill Bill, especially in how it transitions into an instrumental.When Bobert transforms into his Self Defense Mode he brandishes his dual rotary laser cannons and roars like a certain other killer mecha.The same house was shown on 'The Parking' when The Wattersons drive their car into a horror movie in order to find a space. Viewed from the exterior, Carrie's house looks a lot like the Amityville House.Several times Gumball turns his eyes into mouths, apparently emulating the Corinthian from The Sandman.Anytime we flashback to Richard in his earlier adulthood (including 'The Treasure', 'The Hero', 'The Man', and 'The Origins') he's wearing a shirt ◊ with a slightly modified Nirvana logo.From season two on, the logo was changed to ' Bisou' done in the style of the KISS logo. In season one, Rocky's black T-shirt had the logo ABCD, done in the style of AC/DC's logo.The Wattersons' last name is a reference to Calvin and Hobbes creator Bill Watterson.
