"Well, .......... do you know what it is that we need to do?" My guess would be: 1. Move "box_1, box_4, Head and cone_1" in the hierarchy under DoggieBot (in the appropriate places) and 2. Rename them appropriately (except for Head)... Not necessarily in that order.. (1. includes moving box_1 and box_4 under "Head..") Cheers, Diolma Who promises NOT to have peeked.. and if the answer is wrong, I guess that'll prove it..:-)) )
