In the video game world, there are consumer-rating warnings on games for things like "suggestive themes," "blood and gore," "Use of alcohol" and even "mild fantasy violence" (what does that even mean?). There is no acknowledgment of any kind, however, of "ear-splitting shrieks that will follow you down into your dreams" on the box of Raving Rabbids 2 -- and God bless their charming, spastic little hearts, maybe there should be.

You needn't be familiar with the previous Rabbids title to enjoy this ADD-flavored collection of mini-games -- but it doesn't hurt, either. The brain-damaged bunnies have landed all over Earth in a fit of psycho infiltra-tourism (Rayman's here too, of course -- anybody remember Rayman?). What results is a downpour of 60 pop-culture-infused mini-games, about half of which are as funny as they are weird and calculatedly-shrill.

Pick and customize the outfit of your psychotic bunny and strike out for the tourist destinations of the world -- Europe, the US, South America, Asia and the Tropics. There's fun here for the solo gamer -- sort of -- but to really appreciate the game's annoying charm (and to unlock a number of the available game types), you'll need to get your multiplayer on; the emphasis is skewed in favor of the party-game atmosphere, and some of the games are just plain weak without live opponents.

The various regions of the world are nicely presented and arranged here by various associated, more-or-less unflattering stereotypes; there's a scrub-out-your-undies laundry game in the Asia collection, and one of the Europe entries challenges the rude little Euro-bunnies to shake and then drink (via corresponding Wii-mote actions) a carbonated beverage -- before unleashing a cataclysmic belch, blowing out windows and setting off car alarms for blocks. Charmed, I'm sure.

There's also American football, the Star Wars parody "Fart Wars," a slack-off-in-the-office challenge (wherein the rabbids need to shriek, spin in their chairs and generally freak out, only to suddenly snap to attention when The Boss is about to check in on them), various on-rail segments and race games, shooting-galleries of rabbids rendered against video of real-world environs, and at least one instance where the rabbids are actually using their plungers for the, um, correct purpose.

For sheer fusion of entertaining gameplay, humor and paint-peeling shrillness, however, nothing beats the music games, which of course riff on games like Guitar Hero and Rock Band. There you are, air-drumming your Wiimote to the beat -- as a rock band of rabbids onstage squeal and shriek their way through a (surprisingly) full-length version of "Smoke on the Water." Somewhere out there in the cities of North America, right now, there are hundreds (if not thousands) of parents re-evaluating the gifts they bought for their kids, and popping Advil Migraine caplets by the handful.

The controls have been frankly dumbed down a tad, and this -- combined with the fact that certain challenges, such as the balancing-plates-of-food games, lose most of their charm unless you've a full compliment of live players -- makes Raving Rabbids 2 little more than the expected Inevitable Sequel. It's not a Mario Galaxy, rush-out-and-buy imperative -- but if you enjoyed the original you'll find some new challenges (and laughs) here, particularly if you've made some friends since the rabbids last hopped onto the Wii.
