I'm not sure if the thing I found was actually an Easter Egg. I got Yoshi to eat the frog on the title screen. Yep, that was probably one. I thought there might be some in the cartoons, but I couldn't find any. It was nice how Randy made three separate ones. The middle one was the weakest.
It was way too predictable. I do appreciate all the good sprite effects. The best was the last one. It's great to see a callback to the other cartoons. At least I could get the 420 joke. That might be the most well known injoke of all time.
