With the Donatello Battle Pack, we can now have a Rock Soldier army. The heads of the two lighter colored Rock Soldiers are a bit tight, so be careful when assembling. It is good that we have Donatello in the cartoon shade of green like the other turtles. It would have been nice to see one of the Rock Soldier have a green helmet, to be General Traag, but maybe we will get him and Granitor (gray Rocksoldier) in future sets, with Nutrinos maybe. Overall, I love the set, and have gotten 3 of them.
