TwinBee Da!! (ツインビーだ!!,TwinBee Da!!? lit. It's TwinBee!!), also known as TwinBee GB, is a vertical-scrolling shoot-'em-up game released by Konami for the Game Boy handheld system in 1990 in Japan, and in Europe as Pop'n TwinBee in 1994. It is the fourth game in the TwinBee series, following TwinBee 3 for the Family Computer and the only installment for the Game Boy.
Despite the European title, the Japanese version actually predates the release of the Super NES identically titled game Pop'n TwinBee by three years.
