Chao in Space

Chao in Space is a series of fictional movies advertised in various places in the games Sonic Adventure, Sonic Adventure 2, Sonic the Hedgehog (2006), Mario & Sonic at the Sochi 2014 Olympic Winter Games and Sonic Generations.

Description
These advertisements take the form of posters, all of which appear in the city-themed levels of the games they are in. These posters show various Chao species as well as characters that have connections to them, such as Tikal the Echidna and Chaos. The movies appear to star Chao in their main roles and are credited as "Sonic Team films". On the Chao in Space: The Search for Tikal billboard in Sonic Generations and Mario & Sonic at the Sochi 2014 Olympic Winter Games, there are some typos with the names of the characters credited below.
