There's mini Kraids... I can't imagine seeing a mini Chozo, Botwoon, Phantoon (think that's his name), or Spore Spawn. I wouldn't like to have to push every Mini Crocomire into a pit of lava. And now that I think about it, mini Draygon sounds unlikely (though they could've used the babies that bury it). I'll say mini Ridley lookalikes.
