I decided to try my hand at animatronics and make the Trilobite into a bubble-blowing robot. It was a lot of fun because I had never tried to "move air" before so I learned how air blowers work and made my own out of cardboard. I also used a servo motor to make his mouth open and close so that he could literally "blow" the bubbles!
Going through this process has inspired me to make more stuffed animals and puppets which is something I loved as a kid. I hope you will try to make one! It could be a great addition to a kid's birthday party where you could modify the project to showcase their favorite plush or fictional character. :)
