[Dollarama] Dragon Ball Z Backpack Hangers (Keychains?) - $3 YMMV
10 figures total to collect - apparently which figure you get is dependent on the ball number.
1* = planet arlia vegeta or ss vegeta
2* = krillin
3* = majin buu
4* = gohan, goku or ss goku
5* = frieza
6* = cell
7* = piccolo or planet arlia vegeta
Planet arlia vegeta has also been reported to have been found in the 3* and 6* balls.
Happy hunting! Might be easier to find with a dragon radar
