Detana‼ TwinBee

'Detana!! TwinBee' (出たな!! ツインビー, "Here Comes TwinBee!!"), originally released outside Japan as Bells & Whistles, is a vertical-scrolling shoot-'em-up game originally released by Konami in 1991 as a coin-operated video game. It is the fifth game in the TwinBee series and the second released for the arcades following the original TwinBee (the previous sequels were released directly to home consoles). In Japan, Detana!! TwinBee was ported to the X68000 computer in 1991 and to the PC Engine in 1992, as well as for the PlayStation and Sega Saturn in the compilation Detana TwinBee Yahoo! Deluxe Pack and for the PlayStation Portable in TwinBee Portable. The PC Engine port of the game was released for the Wii Virtual Console in North America and Europe in 2009 as a "Hanabi Festival" release.

Detana!! TwinBee marked the debut of Japanese animator Jujiro Hamakawa (credited under the pen name Shuzilow.HA) as the series' primary character designer for every subsequent installment. Detana!! TwinBee was awarded "Best Shooting Game of 1991" by the Japanese arcade game magazine Gamest.
