On the way to Olivine City, a blimp lands in the town that Ash and friends are in. It turns out that there are two sick Pokemon on board and Brock is allowed to treat them. The two pokemon are Kecleon, and after being healed they go on a hiding spree. Not knowing whether or not if they are on the blimp, Ash, Misty, and Brock decide to help find them.

As Ash, Misty, and Brock head to Olivine City, Team Rocket attacks. In the battle, Cyndaquil and Weezing's attacks cause an explosion and Cyndaquil is separated from Ash. When Cyndaquil wakes up it is in an oasis with a Miltank. Ash then sets out to find it.
