Gag Training
Immediately after you finish the Toon-torial, Flippy calls you over to Toon Hall so that you can start learning a new gag! He first tells you that gags will only grow more powerful through repeated use, and sends you off to go defeat 4 Cogs as practice.
After you defeat the first four Cogs, Flippy explains that there are four types of Cogs - Bossbots, Sellbots, Lawbots, and Cashbots - and asks you to go defeat four of one type. Don't worry, he tells you which type to defeat.
Finally, Flippy sends you to another Toon Shopkeeper to talk about your choices for your next gag track - sound or toon-up. The toon will give you a little information about each track, and then give you some time to decide. Choose carefully!
