Experiment #344 - Dupe Lilo and Stitch have managed to capture Experiment #344, who can duplicate anything. This leaves Gantu feeling down, so he goes home to talk to 625 about it. However, 625 gets bored and tells him he doesn't care, causing Gantu to go off in a rage. Meanwhile, Lilo, who has hosted a slumber party but no one turned up, decides to clone herself using #344, but Stitch jumps in the way, creating an extra 3 copies of himself, who all need training. Gantu, in his rage, discovers 4 experiment pods: Heat, Plasmoid, Thrasher and HammerFace. He activates them and plans an attack on Lilo and Stitch. But surely 4 Stitches can beat Gantu.. Right?
