And the project in action:

The fun part of this project is you can animate any Animal or object you want. Do you want a cat, dog, cow? It's possible. Paper, plastic, 3D, that works very well.

You can also animate other objects like small robots. With Trinket, pins #3 and #4 are free which allows for additional servos. Continuous rotation servos may be used to move forward and backward.

You can animate several parts with one servo using the round servo horn with multiple holes and wires.

Post your creations in the Trinket Adafruit forum.
