Treasure hunts were searches for bonus items that reflected new islands on Poptropica. They have not been used for some time, although bonus items occasionally appear.
The latest bonus item (June-August 2010) was the Hypno costume. To get it, you would go to Early Poptropica, to Poptropica Towers on the far left, and to the 4th floor of the green building. The center window has a flowerpot on it. Pressing the upper left pane of that window gives you the bonus item.
A treasure hunt usually looks for a valuable treasure and scavenger hunts look for many unvaluable objects.

There is no Treasure Island in Poptropica.
There have been several famous treasure hunts with clues contained within books. One of these is entitled "The World's Greatest Treasure Hunt" and the net proceeds of sales of this book are going to Cancer Research. The first treasure hunt is for a solid gold Golden Eagle worth about $8m.
