This seems to be the most popular island to speedrun, so I will put a guide here for those of you who wish to speedrun it.

Go right to Early Poptropica, go down the well and get the glowstick. Go back up, left to Main Street, and down the manhole. Drop down, go to the right and get the Prized Porker. Jump over the spider, go left, traverse the maze to get the Golden Egg. Go up, then hop all of the buildings until you get to the top of the blue building. Head up the vine. Give the purple giant the Golden Egg, then go right and get the water bucket. Do a precise jump off of the pumpkin in order to get over the shovel which saves getting the jetpack. Drop down, get the flag, then head back to Early Poptropica. Give everyone the items, using S to skip through the text, and talk to the guy on the boat to get the medallion.
