Contains examples of:

 * Early Installment Weirdness:
 * In the pilot from way back in 2001, the characters who appeared in this episode have completely different designs and the episode was less than a minute long. The opening and end sequences were also completely different from all later episodes.
 * As with the current show, the character voices were very different (with the most strikingly examples being Jimmy Five and Stan Marsh), and the morals at the end of the episodes were random rather than having something to do with the plot of the episode.
 * Animation Evolution: The first five episodes of season 1 were simple and had stiff animation. Starting with "The Tooth Hurts", you can notice some differences, some shadows, a bit more detailed backgrounds and improving the animations on the characters. In particular, the pupils of Cuddles, Maggy, and Cartman have gotten a bit smaller. Season 2 introduced more facial expressions, more detailed backgrounds, and smoother animation. In the third season, the animation has gotten so much better that the backgrounds look more detailed and the deaths were even gorier than before.
 * All Cloth Unravels: In the episode "We're Cursed!", Lumpy stupidly pulls a thread of Gumball's shirt and it ends up unraveling his entire shirt.
 * Hope Spot: As seen in "Good Point", Monica thinks she is finally safe after entering a party room. However, Jimmy Five presses a red button near the room and he and Monica are history.
 * Growling Gut: Happens a couple of times to Nutty and Maggy.
 * Potty Emergency: Gumball and Petunia in "Cruel Drink" after drink too many lemonade.
