Unnamed Plant Digimon Line

A somewhat redesigned version of the cool plant digimon idea I thought up while stressed out! It was originally kind of a rabbit... shaped.. thing? And now it's just a... I don't even know what it is. But I like it! XD
And I thought up designs for its Fresh and In-Training forms too!
Its sorta like... the big circley things are berries? (Gooseberries? Blueberries??) So it starts off as like a little seed with berries growing out, and then its some sort of creepy mandrake-like flower bud critter with a big berry on its head, and then its a lanky somewhat animallike thingie with two berries for ears.

You can see the original doodle of the rookie form somewhere on my digimon sketch dump: bunni89.deviantart.com/art/The…

The sad thing is that I have NO IDEA what to do with this design, or even what to call any of the forms, or what its powers are, etc. I really wanna give it to one of my OCs as a partner, since I love it so much...
I dunno, maybe this could be the new look for Mika the super pacifistic cowardly snuggleblob? He was originally meant to be some sort of cat digimon so he could digivolve into Leomon, since the entire joke was "lol a cowardly Leomon". But I dunno if that sorta makes him boring cos the only reason he exists is for the sake of comic relief?
And it could still kinda work for this digimon anyway, but it'd just be more like "what a creepy looking digimon... and it's a harmless coward??"
I have to redesign him into SOMETHING original, since the Digimon SKyline group doesn't allow you to use official digimon as your partner. And I think if I just draw a different cat digimon that turns into a different lion digimon then the joke is already gone anyway...
