I found Heart Wings in the pound (currently a female Lasirus), and I wanna make them into one of the Sweetheart pets with hearts on its wings XD Which one should I choose?
Dragarth:
Hipottu:
Irion:
or Lasirus:

or should I hold off deciding until this year's Sweetheart pets are released? I'm too lazy to figure out which pets don't have a Sweetheart color yet XD
I personally like the hippotu best out of the ones you've posted. I really like the heart shape it's making with its wings. Thankfully sweetheart is one of the cheaper colors to obtain if you have candy hearts on hand, so if something better fitting comes along you can always change it.
I love the Dragarth and the Hippotu but I prefer the Hippotu more, it just looks so endearing. I would wait for more colors to be released if I were you, just in case you see something new that you prefer.
I was actually leaning toward the Hipottu, so that's great you both recommended it! I do think I'll wait until Survival just in case something else comes out (plus I'd rather get the potion with hearts than with sP :P), but so far, I like the Hipottu best ❤
And it'll give me time to decide on a minion... so many cuties!
