Wishing to Not Be Small and Weak

A shooting star passed through the night sky. "What do I wish for? Well, I'm tired of being small and weak...hmmm...I wish to be large and strong!" said Jimmy. The next morning had a surprise to Jimmy. A white cloud appeared beside Jimmy, hands holding the atmosphere, feet absorbing sunlight, houses shrinking-No! Jimmy is huge! Thousands of times larger-than-life! There is nothing for him to fear, for his wish has come true! Later, Jimmy starts to get the hang of being big and strong. However, Sarah can't find him. "Where is Jimmy?! Anybody know where Jimmy is?!" shouted Sarah. She spotted Jimmy! "Eep!!! That thing looks like Jimmy, but much too big! Someone, go identify that...thing." said Sarah. "Uh...that's Jimmy." said Ed. "Well if that is Jimmy...that's fine..." said Sarah. "Oh Sarah...is my size bothering you?" asked Jimmy. "No." said Sarah. "What?" said Jimmy. "I said no." said Sarah. "What?" "I said no!" "What?" "CAN YOU HOLD ON A SECOND?!!!!" Sarah went off and returned with a megaphone. "I said no. Anyway, I've got to ask you, how exactly did you get so big?" asked Sarah. "Last night, there was a shooting star, and I wished to be big and strong, and this morning, I woke up with my wish granted." said Jimmy. "You made a great wish. When I first considered you a friend, I knew that good things sometimes come in small packages. In this case, you're like my large friend. Now you don't have those kids to tease you. You could crush them." said Sarah. "Mwahahahahahaha! Your wish didn't come true! I do evil by supposingly granting wishes! I made you big and strong! Now when I brainwash you you'll be the largest of my group!" said a mysterious voice.
