Dude? Probably the Kumos or the Irion for me, holy cow gonna smooch the heck out of them:

I'll be the first to say I dig the Kumos so much because it's provocative, and the Irion for it's bashfulness, something I find killer-adorable. This is also where I'd lavish love on the Sweetheart Montre, IF WE HAD ONE

Sweetheart Harvester for sure! I LOVE the combination of creepy and cute :)

So I love pretty much all of them. >.> I own way more than I thought I ever would. 5 of 27 doesn't seem that much, but previously I'd been trying to limit to 2 of any one species or color... I have a Lasirus, an Antlephore, a Celinox, a Donadak and a Kumos (with a custom overlay). The kumos at one point was an Irion (which I still love), but the overlay being a wolf is what made me want to change it. I know obviously it doesn't matter, it's literally just the word 'kumos' that is displayed, but I'm particular when it comes to my overlays matching what the pet says it is. >.>

is the CUTEST thing in the world, seriously. I love a lot of the Sweetheart pets, but this one takes the cake for me!

I adore the ontra, but I have to just throw out this perf lil boi:

I might be kind of biased though since Estie is one of these. ;u;

Other than the Bumbus though...the first one that came to mind is the Neela!

Mine is between the Lain and the Harvester! So cute.

I might be a little biased, but I adore the Sweetheart Harvester

Sweetheart Archan. So cute, I just want to cuddle it.

I very much like the

Ghostly

and the

Fester

I enjoy most of the colors as they have lots of personality.

Sweetheart Harvesters win life <3

Sweetheart Yaherra and Sweetheart Keeto :3

and

I have to chose only one? That's absurd, they're way too cute to only have a single favorite!

however, I really think these are super darn adorable!

I don't have any Sweetheart pets myself, but I'd go for Jollin if I were to do that.

Love 'em! 8D So shy. So perfect.

Personally I love the Harvester, but my first Sweetheart pet was the Dillema because of the "U FINE" candy heart. I couldn't resist.
