🎨 How to color it

Color the smiling shark sky blue, the little submarine lemon yellow, the round porthole aqua, and the seaweed spring green. Use chunky crayons or markers for the shark’s big body and the submarine’s wide panels, saving a sharper crayon for the tiny porthole bolts and bubbles. Try making the bubble trail lighter as it rises, like the submarine is whispering a secret upward.

The story behind this coloring page

Juno Hears the Tiny Knock — Under the periscope flats, Juno kept a cozy sand dip where the water hummed mmm-mmm against his fins. Read the full story →

Under the periscope flats, Juno kept a cozy sand dip where the water hummed mmm-mmm against his fins. He wanted one perfect engine bubble for his secret bubble shelf, so when a yellow submarine puffed past, clink-clank, he slipped out after it. The farther he swam, the colder the water tickled his belly. He traded his last crunchy kelp chip to a crab guard for a peek at the bubble pipe.

But the best sound was not in the pipe. Tap-tap-tap came from the round window, where nobody looked because everyone watched the bubbles. Inside the glass, a tiny shrimp had wedged a pearl button and was knocking, “Open, please!” Juno nudged the latch with his nose. Out popped the shrimp, the button, and a bubble shaped like a wink. Juno brought home no perfect engine bubble, only a new knocking code: mmm-mmm, tap-tap-tap. If you spot the round window, keep the secret—Juno’s cozy sand dip may be humming back.
