Just in time for the release of “ParaNorman” yesterday, the official mobile game of the stop-motion kiddie zombie movie has been updated with more zombie-rific content.

Released three weeks ago, ParaNorman: 2-Bit Bub is an action puzzle game starring Bub the two-bit ghost-dog.

To be sure, Bub is just a minor character in “ParaNorman,” which centers on the supernatural misadventures of a ghost-seeing boy named Norman Babcock. But in ParaNorman: 2-Bit Bub, Bub takes center stage.

In ParaNorman: 2-Bit Bub, you must help Bub collect all of the bones he managed to take from the town graveyard before the zombies who own them awaken.

In every level of the game, you must slingshot Bub’s ectoplasmically conjoined body onto a series spectral orbs. That way, Bub can climb his way toward the sought-after bones.

In the new version of ParaNorman: 2-Bit Bub, you can now teleport Bub through the new astral orbs.

But undoubtedly the most important new addition in the game is the set of 10 brand new puzzling levels.

And since getting three stars in a level effectively unlocks a collectible poster, 10 new posters have also been added. In line with this, a new in-game star tracker is also introduced in the new version of the game.

The recently updated ParaNorman: 2-Bit Bub is available now in the App Store for free.

And “ParaNorman” is most likely showing now at a theater near you. I hear that, even as it’s about rotten zombies, the movie is quite fresh.
