"What has four thumbs and looooves Frosty Freezy Freeze? Fanboy! Aaaand, Chum Chum!" -Fanboy and Chum Chum[source]
Almost every day, Fanboy and Chum Chum have loads of adventures wherever they go. Some of the adventures are used as a way of helping someone in need, while others are just to help them have the best and silliest day ever.
Fanboy and Chum Chum first meet Kyle Bloodworth-Thomason and mistake him for a pretend wizard. Fanboy pretends to be "Wizboy" and pretends to do some magic. The three also have a wizard-off. At the end, F&C know Kyle is a real wizard.
This is the first time Fanboy and Chum Chum interact with Kyle. Kyle went crazy and threatened to destroy them near the end, but they didn't see this.
Fanboy trades Chum Chum to Yo so he can play with her Mechatech.
Fanboy lies to Chum Chum that he has to go into space to change a monkey's diaper so he can trade him. Later on, the Mechatechs turn against him when he pulls off Yo's Mechatech's arm. This is also the first time Fanboy's superhero side was shown.
Fanboy, Chum Chum and Dollarnator try to write various jingles for the Frosty Mart Jingle Contest. Lenny manages to destroy the final one which they cannot remember, so they sing a cheer-up song which becomes the winning jingle for the Frosty Mart.
This is the first time Fanboy and Chum Chum sing about the Frosty Mart together.
They think Man-Arctica is pretending to be himself and call him "Backpack". Man-Arctica tries several times to get Fanboy and Chum Chum to remember him.
They also compete on Oz's game show, "Are You Man-Arctica?", to which Man-Arctica is believed to be a contestant. F&C manage to remember Man-Arctica by finding Man-Arctica's underwear that his mom made him, along with the closed loop "A".
