GRAMPS AND WILLOW are trying to dislodge a Shrinkinator's gear from the wall of a sand tunnel. Things get dangerous when Gramps pulls out the gear and the sand walls start crumbling. Escaping this risky situation, the two of them join ZAK, CHOWSER AND SYD, who are waiting in the yard. Willow's moment of glorious victory celebration is interrupted when she and the gear are snatched by a fly-by magpie. The rest of the Insectibles, together with Gramps, rush to the tree where the magpie's nest is. Zak masters a fool-proof rescue plan, but much to his surprise, he finds out that Willow may not be as brave as she claims to be. It is up to Gramps and Syd to distract the angry magpie, while Zak and Chowser find a way to get both Willow and the part save on the ground.
