Also, judging by the size of the lighter, those things aren't much bigger than than koyukkuri themselves, so they're either just past the koyukkuri stage themselves, or koyukkuri are trying to have more koyukkuri.
Maybe both panels are actually of the koyukkuris. There's something that looks like a bit of stalk above the hole in the second panel though. I guess a full translation would help clear this up.
