Rickety's granddaughter Racquette is visiting Treetopolis and Rickety is determined to stop her doing anything too exciting. She talks him into letting Tom and Twigs show her around and they start at Ariela's Ranch, where Racquette accidentally causes Teabiscuit to stampede. Then she triggers a jittery pea avalanche that threatens the Castle and finally she causes the cavern coaster to hurtle towards the bottomless pit with her and Twigs onboard. Is she trying too hard?
