If you fell in love with Toothless, the adorable fire-breathing star of 2010's animated movie hit How To Train Your Dragon, PikPok's latest iPhone and iPad app is sure to have you burning with desire.
Dragons: TapDragonTap is a physics-based puzzle game in which pacifist viking Hiccup flies Toothless around the island of Berk, rescuing lost sheep and herding them into wooden pens.
To coax the woolly runaways back to their designated boxes, you must interact with the environment to clear a path and get the sheep moving in the right direction.
For example, you can bridge gaps with fallen trees - after you've burnt them to a cinder first, of course - and drop boulders on catapults to fling some of the lazier lambs towards the goal.
There are over 40 levels of fire-breathing fun to fly through, and a host of collectible treasures and secrets to uncover.
You can 'rescue' Dreamworks Dragons: TapDragonDrop from the App Store for £1.49 / $1.99 now.
