Where's Waldo

What do you think of the idea of a "Where;s Waldo" deco for our island?
We can be able to place it somewhere on island, and "attach" a price to it. First one to discover it can claim the price. (this way, people can also help find collectibles :))
Island should have a way to notify if price is active (like Zone-wide buff Waldo) and what is the price, so people know which island to search.

I think that we don't really need a special decoration for that idea. We have done such things in our guild quite a few times. Also find all the xxxx join the dots and tell us what the picture is. This was most recent:

Have done similar for a competition by placing 10 small decos on my island for guildies to find.
