Gimmick leaves a portable version of the Reducing machine out in the open, and LB uses it to shrink the Trio and the Airship down to miniature size. LB proceeds to ransack Gimmick's house, and discovers five of the Crystals and takes four of them to Tweeg, who plans to take them to MAVO. Meanwhile, the Trio meet up with a group of bugs, who invite them to a dance. There, Grubby meets a caterpillar named Karen and falls in love with her. After a few days, however, Grubby is crushed when Karen disappears into a cocoon and falls silent. Teddy and Gimmick figure out that Karen is about to become a butterfly, and rush to tell Grubby the news just as Karen emerges with her new wings. Karen operates the Reducing machine and restores the Trio back to normal size, and Karen regretfully says goodbye to Grubby.
