"Oh, go on." Platypus wriggled up against Echidna's soft underbelly. "You know you want to."
"It's not natural," Echidna turned away to hide her face, pressing spines against Platypus' sleek fur. "What would people say?"
"Oh, bosh to what people say." Platypus lolled on her back, gently paddling at the air with her webbed feet. "People say I don't exist, or that I've been sewn together from parts of ducks and beavers." She rolled back over to nuzzle gently at Echidna with her beak. "I don't need their definitions, I know who I am."
Echidna peeped shyly from between her claws. "I suppose I've always tried to fit in. But, you know, I'm not just another hedgehog."
Platypus smiled a wolfish grin. "You're so much more."
