April Fools' Day Prank

On April 1st of almost every year since 2009, Poptropica participates in April Fools' Day. This is usually accomplished with a prank centered around Poptropica.

2009
On April 1st, 2009, multiple minor changes were made to the game including: On April 2nd, a post was published to the Poptropica Creators' Blog and a video was uploaded to the VladTheViking YouTube channel, both chronicling the event.
 * the logo on the start screen was flipped
 * all characters in-game were given the Bobblehead effect
 * in addition to the Bobblehead effect, NPCs that run past on the start screen were given goofy glasses.

2010
On April 1st, 2010, a new costume was added to the Poptropica Store named the April Fool. Strangely, this costume addition was not announced on the Creator's Blog.

2011
On April 1st, 2011, a new card was added to the Poptropica Store named the Prank Can. This card allowed the player to prank themself, or prank other players in Common Rooms. This update was accompanied by a Creators' Blog post which was comprised solely of an embedded YouTube video. The video, published on the Official Poptropica YouTube channel, showcases the features of the card.
