The easiest would probably be early poptropica because all you have to do is find the three missing items. (talk to people there for details.)
the mission is on spy island
The first easiest is Early Poptropica, then Shark Tooth, then Big Nate, then Time Tangled.
Unless Poptropica has a new contract with Lego, the mission will not be available.
I think early poptropica is the easiest island
I would say Early poptropica and Shark Tooth
