Night-Light Fright

Night Light Fright is a 4-Player minigame in Mario Party 5 and Mario Party: The Top 100. Its name is a pun on the title of the song "Bright Light Fright" by. Night Light Fright was also playable in the demo of Mario Party 5, under the name Ready Light.

Introduction
The game takes place in a dark alley. A Chain Chomp falls from the sky and barks a few times once it hits the ground, causing all of the lights in the buildings around it to dim. The camera zooms in on the first player's character, then splits to show the other three, then the game begins.

Gameplay
The goal of the minigame is to stop the Chain Chomp that is charging at the player by shining a flashlight at it. Each Chain Chomp starts 30.0 units away and moves at a different speed, so hitting the light at the same time as another player may not work. The player who stops the Chain Chomp at the closest distance to them without getting hit wins. Distance is measured in meters or yards depending on the region of the game. There is no distance counted if the player is hit by the Chain Chomp, so players must keep an eye on not getting hit if they want to win. It is possible for multiple players to win.

This minigame appears in both of the games' Decathlons. In Mario Party 5, it is the fifth minigame, whereas in Mario Party: The Top 100, it is the last minigame in the Full Decathlon. Here, the player's objective is to the stop the Chain Chomp as close as possible to earn as many points as possible, up to 1,000. Though stopping the Chain Chomp at the same distance in both games awards more points in The Top 100, a player that does not stop the Chain Chomp before getting attacked gets zero points, and a player can score 1,000 if they stop it at a distance of 0.1 units. The default record for this minigame in Decathlon is 4.1 units in Mario Party 5 and 10.0 units in The Top 100.

Ending
Once all players either are hit by or shine their flashlights at the Chain Chomps, the minigame ends. In Mario Party 5, the minigame remains split-screen during the ending, the camera zooms out a bit, and the characters who remain face the screen with the winners doing their winning animations and the losers doing their losing animations.

If no one shines their flashlight, the minigame ends in a draw. In Mario Party 5, the word "Draw" appears on the screen and the announcer calls it, while in The Top 100, all players do their fourth-place animations while a remix of the losing music from Mario Party: Star Rush plays. However, if all four players shine their flashlights with all players having the same score, all players get first place in The Top 100; it is unknown what happens in Mario Party 5.
