There are few cultural phenomena on the scale of YouTube Rewind, a head-spinningly packed recap of the video influencers, memes and moments of the year.

Last year’s clip was viewed more than 200 million times, and the newest installment, created again by digital content studio Portal A, is off to a tire-squealing start with nearly 5 million views in its first two hours.

While the Google-owned video platform’s recap is always a bit of a cameo cacophony, there’s typically a theme that runs as a thread through the whole thing. This time around, online gaming mega-sensation Fortnite provides the backdrop, with content creators dropping into a jungle setting via the game’s preferred form of group transit: a school bus hot air balloon.
