If you give a 'bold a gold coin, 

he's going to ask for a hug to go with it.

After the hug, he'll want to take you to his potion shop to see his newest potion.

When you arrive, he'll want to give you a potion to try out.

When you try out the potion, he'll want to take some notes as he watches you change.

After you shrink down a few feet, he'll want to get you some new clothes!

When he gets you a good outfit, he'll thank you for coming and give you another hug...

But giving him another hug will remind him, so he quickly runs to the backroom.

When he returns, he will give you a gold coin...

A cute little drawing idea I had! Thanks to Nyhgault for letting me draw this idea with Max!
