It's the annual sticky bug migration season in Treetopolis, and the streets are full of swarming insects. They seem harmless - but if they are touched, they attach themselves and will not let go! When a bug lands on Zigzoo, Tom and Twigs devise a hands-free plan to save him - using his robot. This fails, so they try some of Zigzoo's other machines, all to no avail. In the end, they change their plan completely, finding the solution to the sticky problem in the bug's favourite food - popple flowers. Show less
