It’s not even September, but we’ve already started rolling out the birthday fun in the Poptropica store.
You can also add the “Shrink Shot” and “Prepare for Impact!” mini-games to your inventory, and play them whenever you want! Just get the cards from the store for free.
And the Steamworks Mech Pilot and Renegade Robot costumes are back in the store for a limited time! These classic looks are only available to Poptropica Members. Find out how you can become a Poptropica Member today.
Stay tuned for more Poptropica birthday fun and surprises!
