Birthday Smarties Puzzle

The Puzzle:

Birthday Smarties

The Birthday Cake has all gone but there are twelve piles of Smarties left. Each pile is held together by icing so can't be split up. Most of the guests have gone, but Hungry Horace and his two friends want to share out the Smarties equally.

Can you draw around the piles so that everybody gets 25 Smarties each?
