Subdued by Three Hats

Hey Big Guy, We went catching bugs on the mountain today! That bug was completely black and shiny, and it crawled like lightning! Little Fu yelled, and Little Shou immediately slammed his hat down to catch it. We were looking right at it, and we definitely caught it! Little Fu and Little Lu were worried the bug would run away, so they hurried and put their hats on top as well. One, two, three hats, stacked perfectly straight! But when we lifted them up, there was nothing there! We don't know what gap that bug crawled out of, but it vanished! We're so angry! You have to help us catch it next time you visit!
