Bag a Bug is a mini-game in Donkey Kong Country 2: Diddy's Kong Quest introduced in its Game Boy Advance port. Bag a Bug is run by Klubba in his Kiosk, and costs 5 Banana Coins to enter.

The game is played as Diddy Kong and Dixie Kong. The main objective is to gather as many fireflies as possible in the area while avoiding Klubba, within the 1 minute time limit. Bugs will be in random locations over the Kiosk, designed as a circle with a small "safe" area in the bottom left corner. Invincibility Barrels occasionally spawn that give the Kongs safety from Klubba's attacks. After getting a certain amount and surviving, the Kongs will be rewarded with bananas, coins, and even Extra Life Balloons.
