THE CREST OF SINCERITY
(Episode 17)

The kids and their Digimon are walking through a barren desert when Gennai appears to tell them that they must take care of their Digimon or they won't digivolve properly. 

Suddenly, a huge cruise ship appears.  Everyone boards it, but it turns out it's piloted by Cockatrimon, one of Etemon's henchmen. He captures the boys and turns their Digimon to stone, then corners the girls. 

Birdramon and Togemon fight him off, freeing the boys and their Digimon, and everyone runs away, but Cockatrimon chases them in his ship. 

Then a giant cactus appears and destroys the ship.  Mimi finds her crest -- the Crest of Sincerity.
