The two frogs

Izu POV

In a hospital
Two nurse role two strollers into a room where the Asui parents sit "here are your two little ones." A nurse says as Ganma Asui picks up a baby boy with cyan blue skin covering most of my body, and a scarf-like collar of frothy white bubbles known as Frubbles around my neck. My front feet are white, and I have a dark blue line on my back that extends vertically across my face. My eyes are large, protuberant and bright yellow. I have two Frubbles on my nose. My back legs are long and powerfully-built for jumping. "He's so handsome." Ganma says with tears in his eyes

(Not my description)

As Bell Asui holds a baby girl with big cheeks a little smaller than Bell's "she's has her mother's eyes while this one resembles me a little nurse is his skin okay?" Ganma says concerned "don't worry Mr. Asui he's perfectly fine it's like your skin it's bumpy and brown." The nurse says before I lifts my front feet trying to touch Ganma, Ganma smiles holding his finger to me as I grabs Ganma finger "how about I name you Izu... Izu Asui." Ganma says hold me in the air as I laugh

As Bell watches them she looks at her daughter "now what should I name you? Tsu... Tsuyu Asui" Bell says letting Tsu grab her finger as Ganma hugs us together
