Disney has just released the first proper sequel to its insanely popular alligator cleaning sim Where's My Water?

It's called Where's My Water? 2, and you can download it free from the App Store right now.

As with the first game, you have to use your finger to dig a path through the earth in order to channel water into Swampy's pipes and out of his shower head. 

This time, however, each of the levels (of which there are over 100) has a series of additional challenges to tackle. These include finding and capturing a Mystery Duck, or trying to complete the level upside-down.

Swampy is also joined by his old pals Cranky and Allie. Allie needs steam to power her pipe organ, while Cranky... Well, he's just a bit cranky.

As Disney has decided to make this a free-to-play game, you'll find your progress halted every now and then by an energy system. You can pay £11.99 / $17.99 to permanently extend the length of the energy bar.

Alternatively, you can either wait for the energy bar to refill automatically, or cough-up 69p / 99c for a quick top-up. If you're really desperate to get back into the game, you can also gain energy by logging into Facebook and getting your friends involved.

If you want to give it a try, Where's My Water? 2 is available on iPhone and iPad at this very moment.
