"Hey! Buddy, look at my new amulet!" Something shining on black wolf's chest.
"Hmm...looks good, it fit you." Metalgreymon turns and looks down the little wolf...from a giant T-rex's point of view.
Weregarurumon"I met someone and he gave me this amulet. He said it can makes me looks stronger...well, I hope it's true."

"And make you looks bigger?"
"Shut up!"

Two beasts watch the sun slowly go down, Not long after, a big moon is rising.
Metal Greymon"Wow, the moon looks quite bigger today..."

"Yes...so...big...big..."
"Buddy? Are you okay?"

Black wof's body is trembling. Suddenly, this wolf looks bigger and bigger! Both of them wide open their eyes.

"What...what happened! You...you're..."
"I...I feel great! Give me more! More!"
"You scared me buddy...you're getting bigger!"

Black weregarurumon keeps growing, he looks even taller every seconds. His body also looks wider because of growing muscle.
When Metalgreymon comes to himself, a huge wolf is same tall as him...or a little bit taller than him!

"What the...that amulet REALLY makes you bigger! How come! It's unfair!"
"Nothing unfair, buddy! HAHAHA! We're just same height now!"
"All right all right, hope it's over...wait! You're just getting...taller?"
"HAHA! I think so." Blackweregaruru grows again...
