In a hot desert, a small lizard named Leo was very thirsty. He lived near a big volcano that had a secret lair inside. One day, a funny dog named Max ran into the desert. Max was lost and looking for water. Leo said, "Follow me, but be careful of the monster!"
The monster was a giant sand creature that stole all the water. It lived in the volcano lair, which was dark and scary. Leo showed Max how desert plants like cacti store water in their thick stems. "We must find shade," said Leo, "because the sun is too hot." Max panted and said, "I need water, or I will faint!"
