Where to find the % key in vim-adventures?

I am in level 7 in vim-adventures. I need the % key to progress. I cannot find it.


The % is locked up to the left of the if(practice){perfect} puzzle. You'll need a key to unlock it.

To solve the if(practice){perfect}, you'll need either % or g, both are locked up. You'll have to unlock one, solve the puzzle, get another key, then unlock the other.
