Hey! I love that idea—glitter glue will sparkle like bioluminescent plankton. For the mystery creature, imagine a translucent octopus with tendrils that glow faintly, each one ending in a tiny lantern shaped like a coral polyps. When you flip the paper‑mâché, the lanterns light up, revealing a tiny hidden reef scene on its mantle. It tells a story of a secret sanctuary where the ocean’s quiet voices sing to those who can still hear. Let's make it glow!
