Gulzar begins by sending out a Gloom. Knowing that Gloom is weak to Fire and Flying attacks, Ash intends to send out Charizard, but Squirtle is sent out instead. Sticking with Squirtle, Ash decides to use Water Gun, but the attack instead refreshes Gloom. Recalling Squirtle, Ash tries once again to send out Charizard, but he accidentally drops his Poké Ball onto a rock, cracking it and releasing a sleeping Snorlax instead of Charizard. Ash attempts to wake Snorlax up, but the Sleeping Pokémon continues to snooze. Gulzar, desperate to get the battle started, has Gloom attack Snorlax with Solar Beam, and the impact causes it to wake up. However, it crawls towards Gloom and attempts to eat it, forcing Gulzar to recall Gloom. Still hungry, Snorlax eats Gulzar’s knapsack lunch and his head of flowers, infuriating Gulzar to the point of tears. Ash tries to return Snorlax, but as Snorlax’s Poké Ball is damaged, it cannot return. Gulzar, fearful for his life, flees and taunts Ash and his friends, claiming the nearest Pokémon Center, where they can have the Poké Ball repaired, is over a mountain.
