Don't miss the stunning, riveting, hilarious, and 100% fresh conclusion to the interactive Spaceheadz saga! The SPHDZ accomplished their goal of recruiting 3.14 million and one SPHDZ. But the brainwave has been stolen by the chief of the Anti Alien Agency, and it's up to Michael K., the SPHDZ, and their allies to get it back. With three potential Chief sightings, the team is spread around the world, leaving Michael K., Venus, TJ, and the SPHDZ to hold down the fort and finish fifth grade. But with a mysterious new principal and graduation fast approaching, will they be able to find the missing brainwave before the Chief uses it to destroy a planet?
