Image & Form, the makers of the SteamWorld series, have released a mysterious video to welcome the weekend.

The company asked fans to watch the video and guess the riddle behind it. Here’s the video:

The most obvious clues to the riddle are the December 10, 2015 date which happens to be the release date for SteamWorld Heist and Neon Blue Joy-Con. This is most likely a teaser for SteamWorld Heist.

The other clue which is least obvious is a Disney Infinity figure at the start of the video and a Mario plush at the back of the room, which could be hinting an amiibo release. Image & Form has repeatedly expressed interest in making an amiibo during past interviews if given the opportunity, so it’s not out of the question.
