Here's the fun part: now available on the online Poptropica through Home island is the Colorizer, now for free (just go into the New You shop). Previously, if you wanted to recolor your hair or skin color, you had to splurge in the store to buy the Colorizer, or visit certain places in the game that did it.
And a quick word on the topic of Poptanium stashes -- in Poptropica Realms, it's possible to share worlds that you've created with the public. Poptanium is the currency that is needed to build anything in your realm, and there's a tool that lets you place Poptanium bricks into your realm, which can be collected later. So you can "give" Poptanium to other players by putting Poptanium bricks down and then sharing it! Brave Seagull has done just that, with an enormous world that not only looks good, but is filled to the coffers with pyramids of Poptanium that you can collect. The code is 9thzx., and according to Slippery Raptor's estimates, you can collect up to 4,630 Poptanium from it!
