Hero, My Pet
 

This is Hero, my pet.  It is a green iguana,  but its name doesn't represent  its colours.  It is brown with a faint black band around its tail.  Hero is 40 cm long and about 2.5 kg.

It likes vegetables very much. Hero eats water spinach, carrots, cucumbers and other vegetables. I sometimes give Hero some small insects. They are good for Hero's bones,  so it won't  suffer from osteoporosis.

Hero looks like a little dragon. It has scales on some parts of its body. It also has strong legs.They are useful for swimming and climbing trees. 

What  is  the  pet?
