An incredible 45 sets were released within the LEGO® NINJAGO® theme in 2020; that’s a lot even allowing for magazine cover mounts and the perennial pocket money “character spinner” variants. It’s a number exceeded only by LEGO Friends sets, while LEGO Star Wars languishes just behind with 43.
The 71720 Fire Stone Mech is one of the larger sets in Ninjago's 2020 ‘Master of the Mountain’ subtheme. He’s a big fella too, weighing in at 667g with a total of 968 pieces including 5 minifigures, all for a comparatively reasonable £64.99 / US$69.99 / 68.23€.
