Lifesaver (Japanese: ありがとうカイリュー) is the name of a Pokémon-based application for the e-Reader. It contains a short cartoon starring Dragonite. Only two cards are required for the Lifesaver application: Dratini and Dragonair.
There are two different versions of Lifesaver. After the card is scanned, Version 1 will play, and when the application is replayed, Version 2 will be played. If the application is replayed subsequent times, this order will be repeated.
Dragonite is flying across the skyline of a big city and then over a big field with windmills. It notices a Pikachu drowning in the water, so it flies down, grabs Pikachu, and brings it to safety on dry land. Pikachu thanks Dragonite and it flies away.
Dragonite is flying across the skyline of a big city and then over a big field with windmills. It notices a Pikachu drowning in the water, so it flies down and grabs Pikachu. As Dragonite is lifting Pikachu, it discovers that a Magikarp is holding on to its tail. Slowly a chain of Pokémon is revealed: first Pikachu and Magikarp, then a Marill, a Goldeen and finally a Wobbuffet, all hanging on to each other.
