Who doesn't want a giant rubber duckie? We know Sesame Steet's Ernie would. The problem is that while it's a lot of fun, a giant rubber ducky has a top speed of 0.0-miles-per-hour in the water. That's why Ryan & David figured that they should attach a motor to their giant rubber duckie and give it some power in the water. While it looks fun, it wasn't without its flaws.
