A group of Betamon live together in a village known for having beautiful flowers. They lived happily together and played with each other every day. One day an Ogremon comes across the Betamon village and originally assuming it was an abandoned field decided to take all the flowers. After learning the Betamon live there it becomes pissed off that the Betamon had found them first and decides to kill them all so it could have the flowers for itself. After Ogremon beats up some of its friends, one of the Betamon summons up the courage to fight, suddenly digivolves to Dinohyumon, and defeats Ogremon. Ogremon, realising it can't have the flowers decides that if it can't have them, no one can – and destroys them and then leaves, swearing it would one day get revenge on Dinohyumon. The other Betamon celebrate Dinohyumon's digivolution, happy that as it was so powerful it could protect the village from Ogremon if it ever showed up again. Dinohyumon however, was a coward, and didn't want to do this so left the village stating it would get new flowers to replace the old ones though this was just an excuse to leave. Ogremon one day returns and attacks the village and was now even more powerful, having absorbed many flowers all over the Digital World. Dinohyumon returns just in time before any of them are killed though Ogremon uses its new power to warp digivolve to Titamon and defeat Dinohyumon. Dinohyumon had arrived with Biyomon, who made flower bouquets, and Biyomon angrily warp digivolves to Phoenixmon and rather than kill Ogremon, uses its "Starlight Explosion" to purify Titamon, turn it in a nice Digimon, and revert it back to Ogremon who then flees. After the battle Biyomon convinces Dinohyumon to tell the Betamon how it feels and is able to tell that them it isn't a super cool awesome warrior and that it is actually a coward and just wants things to go back to how they used to be. The Betamon tell it that it is being dumb and that they know it's a coward but that it digivolved to save them and can also be amazing, as well as a coward and that they all just want to continue being friends.
