For the party games, I chose actual names from the levels in the video game and went from there.The first game was Luigi's Purple Coin Chaos! I found dark chocolate Hershey Kisses, bought 100 of them and scattered them all over the room. The kids had to collect all the "coins" that Luigi dropped.Next, Sneaking Down the Creepy Corridor. I taped some Halloween-esqe decorations in the hallway and on the bedroom door that the game was taking place in. When they opened the door they discovered......a room full of Boos!There was a Comet Medal hidden in the room full of "Boos" and the kids had to find it!Then we played Silver Stars Pop-Up. I put together a scavenger hunt to find the five Silver Stars that were hiding around the house. (Side note - I used Sheriff badges that I found at a party store but then found actual little silver stars the next time I went back! Grr!)
The final level was Bowser's Big Lava Power Party! My husband wore the Bowser hat and the kids were supposed to throw water balloon "fireballs" at him until they defeated Bowser. Unfortunately, it rained and we had to move the party inside so we had to improvise with balled up plastic bags. It worked out fine, none of the kids cared as long as they got to throw something at an adult!I made a poster with outlines of everything the kids needed to collect in each level.
Once they defeated Bowser, the kids were awarded the Grand Star for completing all the levels. It was the sweetest reward they could have gotten!
