Having a kid is a lot of responsibility but if you're a man-sized child, it can also be a lot of fun. Take Carsten Riewe, for example, he made a Caterpillar P5000 Powerloader costume from the movie Aliens for his 13-month-old daughter. What's the point of having kids if you can't do crazy things like that!
Riewe explains:
This Baby costume was inspired by the Caterpillar P5000 Powerloader from the movie "Aliens" by James Cameron. The arms and legs are full moveable and the top-light and LED were powered by an 12 Volt battery pack stored in the backpack. The on/off switch is in the left arm. Also in the backpack a Bluetooth boombox ist installed to play mechanical robot sound fx or music if preferred. It took 100 working hours to finnish the costume and I built it for the "Karneval"-Parade in my hometown in Germany February 2014 . My 13 months old daughter enjoyed to be carried and moved in her harnness savely.
