Lilo goes to an Elizabethan Fair with the hula girls, but Stitch can't join her as no dogs are allowed and Mertle refuses to be with Lilo. Stitch and Mertle then team up to fight against a metal-eating experiment.
The tank is awakened when a man is watering the car he wants to sell his old car to two people. The tank then eats the car and grows bigger. Later you will see Tank eating a factory and grows even bigger. Then the Tank walks right over Stitch and Mertle which enables Stitch to go get Lilo and finds to see that she can care less when she wants to hang out with her friends. Stitch decides he needs to fight tank and brings Mertle for some odd reason. They find tank eating all the cars he can eat even attempting to eat the truck stitch and mertle was in. Stitch and Mertle get trapped by Gantu and then later escape and then almost get eaten by the tank. Stitch then fights tank while the tank is trying to eat stitch. Stitch does have the upper hand in the beginning but after stitch throws tank into the lake and the tank walks out. Tank grabs stitch with its tongue and attempt to eat stitch. Stitch attempts to escape by keeping the tank's mouth open while the tank is trying to close its mouth. The tank wins by opening it's mouth causing Stitch to fall back in and then tank then proceeds to chew stitch and later then spits him out.
