A teaser of Wander Over Yonder was shown at SDCC 2012.
It was recorded and put up on YouTube multiple times, each resulting in either a copyright takedown or a simple deletion by the uploader, before finally popping back up on YouTube in 2015.
It first shows Wander riding on Sylvia, but they suddenly stop at a tiny bug-like alien. Wander and Sylvia then greet the alien. They then notice an army of Watchdogs chasing after them, they fly off a cliff using their Orbble Bubble. They cheer as the Watchdogs fall off the cliff. The duo are later seen flying into space in their orbble bubble, before the logo fades in.
Trivia[]
The only dialogue for the trailer is "Whoa", said by Wander and Sylvia.
This trailer has an early design for Watchdogs, who were originally a lot more mechanical looking, had shiny helmets and their eyeballs were completely separate from their body.
