"Maybe only in their own dimension?" says Darian dubiously. "I don't know. I'm not a cartoon expert. Or a penguin expert."
"Not in their wings, I think. Maybe in their beaks. They carry babies on their feet! Baby penguins, not baby people."
"I think someone would find it worrying if they carried baby people around on their feet. Do the baby penguins find it strange? How do you walk when you're carrying a baby anything on your foot?" He looks down at a foot. "... I don't think my feet are big enough."
"Yeah, and that's why they help out. Because they have hands and the penguins don't. And they're friends and help each other out."
"... Dance?" says Darien dubiously. "I don't know, you're the penguin expert, what do penguins do?"
"I don't know, they don't seem very useful. I'm not sure what they could do that leprechauns can't besides being in zoos, and that doesn't seem like a nice thing to do to the cartoon kind."
"No, it doesn't." Darian thinks deeply on the possible uses of flippers. "... Maybe they use their flippers to fan the leprechauns? If they're hot or tired."
"But penguins are from really cold places. If the leprechauns are too hot the penguins are probably dying."
"They need to know where the rainbows are so they can find their gold, which is magic. Maybe the penguins look?"
