The boy leaves the pet store with the iguana in a large cage.
Then a small 4 inch tall ghostly figure of a woman appears in front of the iguana.
I am here to give you the power to make yourself, other animal, and people any size you want.
And if you don't believe me use it on someone or maybe yourself.
At that time the boy gets too his home and puts the large cage with the iguana in his room.
the boy leaves the room.
Then the iguana thinks of himself shrinking smaller so he can get out of the cage.
He then starts to shrink to 1/2 inch. Then he get to the edge of the cage and sees that he would have to jump down. He gets a idea why not jump and make himself bigger at the same time. He then jumps off and thinks himself to grow. When he get to floor he is normal size. The boy comes back and sees the iguana on the ground. The boy then pick up the iguana. The iguana starts to thinks of himself growing bigger. As the boy is about to put the iguana back in to the cage he starts to grow. The boy sees this and drops the iguana. When the iguana is on the floor its half the size of the boy and growing when the iguana does stops growing he is the some size as the boy. The length of the iguana is the same as the room.
