Additional Interactions

 * If a :) object is on (or is) a U object, the lvl will be won.
 * ( and o both parse before :), so if either is activated at the same time as :) then one object will be destroyed and the lvl will not be won.

Appears in Lvls:
All lvls (citation needed)

Trivia

 * It's referred to as 'yay' in the source code, and is probably pronounced that way due to being rhymed with GAY in poem4u!
