Make it KOO
From Toadwater Guide
Many explanations have been put into this mysterious button. Famous ideas:
"It makes nosy newbies ask stupid questions." - Youngling Ruinarcle
"It makes you cool, but it also requires seven rolls of masking tape, 1 kudos bar (The good kind), and some spicy american lamp sauce. It's prerequisites are that you must have already been cool.
Too late. Grin" - BlackRaveness
A philosophy of the mysterious "Koo":
"Think of "koo" as a department store santa. The kids are entertained and the adults think its cute to play along." - Dormcook
There are nonbelievers in the crowd. For example, Judge Faust.
"The "make it koo" thing does absolutely nothing at all. It's probably a remnant of a game improvement that was once planned but never implemented." - Judge Faust
