The track originates from the Nintendo DS game Club Penguin: Elite Penguin Force, a spin-off game to the now-defunct children's MMO Club Penguin. It is used whenever the player is inside the Gadget Room of the Penguin Secret Agency Headquarters, or Gary's Room at the Sports Shop's second floor, both owned by Gary the Gadget Guy. The track would reappear in the game's sequel Club Penguin: Herbert's Revenge.
The composition features mostly instruments from various Roland sound modules, notably the XV-5080.
Before 2020, the meme was largely pushed by TTGD's top contributor, Retro Gaming. In early 2020, TTGD had a "Gary the Gadget Bot Takeover", featuring over 200 rips involving "Gadget Room", as a parody of SiIvaGunner's Inspector Gadget Takeover from 2017. This popularized the meme on the channel after the event, and influenced its use on SiIvaGunner.
The "Gadget Bot Takeover" had a sequel three years later, called "Gadget Week 4 & Sunny". Taking place from May 14 to June 4, the event featured over 400 rips, all centered around the track "100 Sunny". While not reaching the same extensive coverage as TTGD, "100 Sunny" still gained memetic status on the SiIvaGunner channel.
The track had been used 13 times from before its increase in usage after TTGD's Gary the Gadget Bot Takeover. Additionally, the track itself has been ripped 10 times.
