The Crest of Sincerity

The Crest of Sincerity is the seventeenth episode of both Digimon Adventure and the Digimon anime series.

Summary
The next stop on the kids' journey is a luxury cruise ship travelling the length of the desert, where the group decide to rest after a long walk. However, the ship is run by Cockatrimon, a follower of Etemon, who begins taking out the kids and their Digimon, turning them to stone. When only the girls of the group and their Digimon are left, they manage to defeat Cockatrimon. They think they've escaped until Cockatrimon steers the ship towards them. So the group hide behind a large cactus, which causes the ship to be catapulted into the distance, along with part of Etemon's Dark Network. It then turns out that Mimi's Crest of Sincerety is hidden in the plant, much to everyone's surprise.
