* Change 1 Part Black {30361 Brick, Round 2 x 2 x 2 Robot Body - Undetermined Bottom Type to 30361c Brick, Round 2 x 2 x 2 Robot Body - with Bottom Axle Holder x Shape + Orientation}
Comments from Submitter:
This part is held by an axle, so its visible position will indicate which variant it is. In set images and in the instructions, it shows the "c" variant. This is also confirmed by a You Tube set review.
