You are assigned to go see Gus Gooseburger at Affordable Goosebumps which is on Walrus Way. As you speak to Gus, he reveals that an incident with turnip bread has made Grumpy Phil mad at him and he wants to make amends. He suggests defeating 3 4+ story Cashbot buildings because Phil hates Cashbots. After doing so, you go tell Phil at The Frozen Nose on Sleet Street what you've done.
