Jeremy grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew and grew right till his growing stopped...
At around 60 feet tall.
He was now as huge as the Amazing Colossal Man, for he had liked the 'Amazing Colossal Man' film as a kid.
"Wow." Lucille said in awe. "Honey, you're so huge!"
"You the same size as the Amazing Colossal Man, now!" Izzy said excitedly.
Jeremy smiles, since he was now so big, he could run and jump and see over buildings.
And his clothes had grown with him, so they fit him. Especially since he didn't feel like going around au natural as a giant.
