Amazon.comYou'll need to pack more than your Dr. Dentons and your Barbie sleeping bag if you choose to be bunkmates with the twin titans of the kid-vid market via the purchase of their You're Invited to Mary-Kate and Ashley's Sleepover Party. The first six cuts on this cute-as-a-bug collection sit right with a slumber-partygoer's sensibilities, probably because they're lifted from the twins' video of the same name: a bashful guest is persuaded to "twist like a tornado and do the mashed potato" on "Dare to Dance"; a pizza complete with guacamole, fish sticks, ketchup, egg foo young, and chicken tongue is whipped up on "Gimme Pizza"; and the inevitable bargain to stay up all night and "paint faces, make up funny names," and dabble in "a zillion cool video games" is struck in "Pullin' an All Nighter." On tracks 7 through 14, though, the sleepover's whereabouts become sketchy--"Step Right Up" and "Mummies Have Mommies Too" take place in a fun house (they're from The Case of the Mystery Fun House video), and those who RSVP'd in the affirmative are also shuttled off to the beach ("Wild, Wet, Wacky Wonderful World" and "Sand, Sand, Glorious Sand"), a hotel ("Why Can't We Live in a Hotel All the Time?"), and subjected to an insufferable heat wave ("Stayin' Cool"). Still, Sleepover Party delivers ample doses of adventure and its adorable hosts couldn't be more companionable. An excellent bet for beating the 7- to 10-year-old blahs. --Tammy La Gorce
