Common: No Common Mutation: GA Bib, GK Bib, GS Bib, WA Bib, WD Bib, C Bib Special: Series Mutation A What?!! A Series Mutation?!!! A series mutation is a series of the same bear released slightly different each time. The first series mutation to be released is Pivot the Netballer Bear. This is the Pivot with a Centre bib. The first Pivot to be released has a Goal Defense bib BUT you can also get a pivot with Goal Attack bib! Eventually you will see the other positions appear in stores so keep your eyes out! Have you got the whole team?!
