🎨 How to color it

Color the crab a bright coral red, the tall seaweed emerald green, the branching coral lavender, and the little fish golden yellow. Use sharp colored pencils for the thin coral branches and seaweed ribbons, then switch to broader strokes for the crab’s smooth claws and shell. Try making the bubbles pale blue at the edges and nearly white in the middle so they look light enough to float upward.

The story behind this coloring page

Nico Shares the Big Bubble — Between the elbowing corals of the reef arcade, Nico tapped one claw on a flat stone: tik-tik-tik. Read the full story →

Between the elbowing corals of the reef arcade, Nico tapped one claw on a flat stone: tik-tik-tik. He had given himself a splendidly silly challenge—blow one bubble so round that every fish, sponge, and shy worm would see it before it popped. He puffed through a twisty shell. Blorp! The bubble wobbled away, smelling faintly of salt and breakfast kelp.

It drifted past ferny seaweed and a row of tube sponges. Nico scuttled after it, waving both claws like a parade captain. “Keep going, you shiny wobble!” he called. Little fish followed, snickering silver flashes. The bubble bumped a coral knob, bounced, and somehow grew bigger, rounder, and louder.

Then Nico heard it: not a pop, but his own giggle rolling inside the bubble—hee-hee-honk! Every creature it passed began laughing too, until the reef arcade shook with joy. Nico lifted his claws higher, sharing the sound on purpose now, and next time you spot the bubbles above him, don’t they seem ready to hee-hee-honk?
