Where's My Water? is one of the biggest hits in the App Store and Disney is celebrating Swampy the Alligator's birthday with a brand new update.

The fun water-based physics puzzle game now includes more levels for you to play. Here are the details from the game's iTunes page:

HAPPY BIRTHDAY SWAMPY! Celebrate with Swampy and his pals! Look for a special gift on the main menu and help Swampy blow out the candle on his birthday cake!

The Lost Levels are getting bigger – now with 10 more levels for FREE! Also if you purchased the Mystery Duck mode enjoy 40 more levels. That’s over 140 levels in the Mystery Duck mode with more on the way.

See the birthday present in the title screen? Clicking on it will take to you a bonus birthday level. One thing that seems to be upsetting players are the constant pop-up ads requesting you purchase the Mystery Duck. Perhaps they'll fix that in another quick update.
