Sometimes a magic user will split a hole through the fabric of time creating portals..But they can also open randomly..and no one knows why..!
a portal appears the dimensions
Sometime animals walk in...or fall in..
It sends u to the inner world where you can enter any of the other dimensions!!
Some dimensions change you..like ur clothes...or ur body...but that doesn't normally happen!

Thats how sunny met pancake..Pancake fell through a portal!
