The ones I love and have:

The dragon, coeurl kitten, dust bunny, infant imp, tender lamb, caith sith doll, Hoary the snowman, wind-up airship,

The ones I love that I want to get:

Treasure box, puff of darkness, wind-up succubus, black coeurl, wind-up Thancred.

Also, I'd love it if SE were to make a magitek colossus minion, they look so massive and badass, I can easily imagine the minion version looking threatening with its axe following me around.

I would need to do hunts to get both the treasure box and the wind-up succubus.
