Forum:What is it?

Hello everyone!

More than a decade ago, I was watching a nice anime. Two months ago I remembered the name: Digimon. When I tried to find EXACTLY what I was watching, I learned that there are lots of different animes and movies. I was wondering if fans could manage to pinpoint me the right one with the only two clues that I have...

1/ I remember watching something in multiple parts: I only watched the first one though

2/ In this part, it ends with the kids and their DigiMons getting poisoned and being circled by ennemies.

That's pretty much it, but I thought I would be enough. Finally, I'm pretty sure one of the DigiMons was Tsunomon (thank you google), but evolved in the yellow/blue form, with a yellow horn.

Hope you guys can help me!

Tank you in advance
