Easy to assemble. This little box will have three new characters to complete the collection of Lego Chima my children. Each of them has a weapon. One of them looks like a gun also sends a projectile. The group also has its lions flag and a sort of small cannon that sends patties: yes yes it's been over crepes that Danish toy but a priori in the words of my children this is very effective against the enemy that it is fire or ice
