He comes to announce the once in two decades Synchronization Celebration! It is the time when all the worlds align perfectly and they are having a huge party in the Wumpa Islands and want to invite the Skylanders. But Dr. Neo Cortex has created a sinister machine to harness this incredible energy for his own evil purposes, only to watch it go completely haywire. Now Dr. Neo Cortex must partner with Crash Bandicoot to stop the machine before the Wumpa Islands are completely shaken apart.
