Ash comes to a town in the middle of a drought. He tries to solve the problem. But doesn't want to injure a helpless pokemon. Unfortunately Team Rocket would.
Ash went to an old man who was playing a Pokeflute, which can wake up any sleeping pokemon. But when he returned Snorlax was hurt. The 2 steal Snorlax.
Jessie smiles "Snorlax snoozed and now you lose!" They do the Team Rocket motto and send out their Pokemon. Ash easily takes out Arbok and Weezing. Snorlax is sent out and beaten thanks to the fact it was weakened and only recently caught.
(A/N I wanted Team Rocket to be less pathetic so I gave them Snorlax)
Ash has Charmander burn the vines blocking the way. Solving the drought. For solving the problem Ash is treated to a free meal, so are his Pokemon
