As requested by JohnnyBGood here is Soundwave. Sadly all 5 minions do not fit inside and 2 barely fits but I think it turned out pretty good. I created 2 more minions a rhino and a lion. As always I welcome suggestion for my next transformer.
Step 1: The Body
Just a simple box
Step 2: The Arms
Step 3: The Legs
Step 4: The Head, the Weapon, and The... What Is This?
Step 5: The Minions
Step 6: The Assembly
The shoulder flaps should be connected in robot mode and disconnected during alt mode
Step 7: The Transformation
Sorry, move the legs on the lion
