In this eat-'em-up, you take control of a humongous worm that loves to munch on people, animals, cars, and anything else it can fit in its gaping gob.

Super Mega Worm is basically an interactive scene from the movie Tremors. You have to travel through the ground and pop out to gobble up unsuspecting victims.

This app now also features follow-up Super Mega Worm Vs Santa, which includes new levels, additional achievements, and that fat guy who comes down your chimney once a year without your permission.

In this extremely good physics-puzzler, you have to propel a strange race of spherical creatures called Mokis into portals, using bombs and a range of other objects.

Naturally, each of your bombs has a unique effect, so you'll have to utilise your entire arsenal if you wish to make it through all of this game's levels. If you're really good, you can unlock Game Center achievements along the way.

iBlast Moki 2 also allows you to create your own levels and share them with the rest of the world.
