And that's not all! As the grand finale of "Five Nights of Fun," some Chuck E. Cheese Reward Members will get a chance to win the ultimate party of a lifetime by hosting their own private "late-over" kids-only party. The Chuck E. Cheese Big Night of Halloween Fun party will be on October 27 from 8pm until midnight for up to 10 kids. This unforgettable experience will include pizza, drinks, playtime for the entire party, slimy-fun Boo-Tacular Halloween treats and, of course, an appearance by Chuck E. Cheese himself and maybe even a special appearance by everyone's favorite purple guy, Mr. Munch.
