Be careful with what your doing. Those bots were designed for a specific driver board to run them. Motors are inductors so they have spikes and other factors that can damage the Arduino. For better use put capacitors between the motor outputs.
There are also no switches to let you know when the motor has completed to the end of the position. The plastic on the inside is very fragile. If overdriven you break him internally.
You know technically you can get a huge Animatronic by doing this I don’t know if it will work So that miniature Animatronic for a loony bird, then sell loony bird for mizi mozzarella
