The gang is moving to the Battle Arena. Still, Brock, May and Max are exhausted and want to rest, but Ash still wants to get the 2nd Frontier Symbol. Later, however, Ash is exhausted as well, so they rest. He asks for water, but there is no water left. Brock, May and Ash leave Max with the Pokemon (with only Mudkip coming) to feed. After the search, Mudkip found a river. Meanwhile, Max gives them the food, telling them they need and goes to rest. Pikachu tells the Pokemon which one is first, though all Pokemon want to eat. However, Munchlax ate all the food. Pikachu goes away and Corphish is angry at Munxhlax, even more when it goes to sleep. Corphish uses Bubble Beam, but Munchlax goes to sleep, so the attack hits Squirtle.
Squirtle counter-attacks with Bubble, so Corphish uses Harden. Pikachu tries to wake Max up, while Corphish uses Bubble Beam and Squrtile uses Bubble. With all the trouble, some Geodudes begin to be angered and surround them.
The dub title is a pun on the educational product Hooked on Phonics.
