Hi there! Let me tell you about a special lizard called the frilled lizard.
When a scary animal tries to catch the frilled lizard, the lizard opens up a big, colorful flap of skin around its neck. This flap is called a frill.
The frill makes the lizard look bigger and more frightening so that the scary animal gets scared and runs away.
It's like when you make a big monster face to scare your friends in a fun game!
So, the frilled lizard uses its frill to protect itself and stay safe.
