A couple of new Ninjago the Movie Polybags have been found, joining the already known Ice Tank.  One of them is the Quake Mech (30379), a bag with sixty four pieces that intends to be a miniature of the bigger Mech (70632) that will be available only in the beginning of the next year.

The second is the Green Ninja Mech Dragon (30428), a small set with a  similar piece count, only sixty pieces, and all the main shapes of a green dragon that can be seen with more details in the regular set, Green Ninja Mech Dragon (70612).

Have a look at the pictures:
