Ben 10 Guardian of the Universe

Got this Ben10 Guardian of the Universe playset as a birthday present for my small one. Comes with a minigun (not that good although can work), a working watch which can fires discs, two great looking Ben10 Monsters (with LED) and a Big badge with multi-color LED in the center - maybe the kids know how to use this in their imagination.
Somehow my kid just play with this set for 30 mins (but continue next days)

Like those monsters
