The game is afoot in brand-new 20-level expansion for Where's My Perry?

The platypus P.I. at the heart of Disney's water-based puzzler Where's My Perry? has 20 new cases to crack thanks to a recent update.

Unlike Swampy, the hygiene-conscious star of Where's my Perry?'s labelmate Where's My Water?, Agent Perry is more concerned with powering his transport tube than taking a shower.

Now, courtesy of the A Platypus Never Forgets level pack, fans of the soggy sleuth have 20 brand-new puzzles to solve - completely free of charge.

If Perry is to make it back to headquarters, you have to charge up his transporter via an all-new mechanic: redirecting laser beams with mirrors.

Reward junkies will be delighted to discover that an extra achievement has been included in the update, plus two extra bonus levels for master detectives.

You can join the fedora-wearing flatfoot on his continuing adventures by downloading the update from the App Store now.
