Author's note: Hi, sorry I didn't update. I had to go to bed early so I could get up early for a trip. Anyway, all of you that have read my fanfiction, review and tell me what you think I should add. If you think that I am missing something then tell me or you can just give advice on what to correct. Thanks.

"What. The heck. Are you talking about!" Calvin yelled. "I never signed up for this warthogs or whatever you said"

Professor McGonagall held her breath to stay under control, "Hogwarts. You didn't need to sign up, you are a wizard and you must go to one of the schools for witches and wizards."

Calvin stopped, then he started to smile, His shoulders started to shake, and suddenly he burst out laughing. "I get it! You two are trying to prank me! You almost had me there. That was a good joke but now that I know that it's a prank then you can just go back to your home and I can get back to my club house."

" I assure you Calvin that this is not a prank." Professor McGonagall said calmly.

Calvin started laughing again, " Oh yeah? Then do some magic! What, you going to say 'Hocus Pocus' or 'Abra Kadabra Alakazam'?"

Professor McGonagall sighed and promptly turned into a cat. Calvin saw this and he stopped laughing. The cat turned back to Professor McGonagall.

"Now do you believe me?" Professor McGonagall asked.

"Yes." Calvin said. "Wait, is that why you can see Hobbes even though no one but me has ever seen him as a living creature?"

Professor McGonagall Explained, "You have a great deal of magic, you have been able to do magic at will almost. However without a wand you were almost always unable to cause it to act to your wishes. For instance, the deranged mutant killer snow goons, or when you duplicated yourself, or when you transmogrified something, or even the time travel. Only those with magic could see them because most of your magic is put into Hobbes. He isn't technically real but with your magic you gave your stuffed tiger a personality and his own thoughts. But so much of your magic was to give him his own personality that no one could see the things that you see. If you were to leave him alone for more than a month then he probably would run out of magic energy and would revert back to his original state. With a wand you could do more magic and give him enough magical energy that he could live his own life and be seen by others as well."

"Wow." Said Calvin. "When do I start?"

" You will need to get on the Hogwarts Express at platform 9 and ¾ at kings cross in London in one week with all your supplies which you can buy at Diagon Alley. I shall take you there tomorrow. Good day Calvin and Hobbes."
