Prepare the lemon Jell-O according the the package directions. Divide evenly among 4 - 8 ounce glasses. Refrigerate for 1 - 1½ hours, or until set.
Prepare the orange Jell-O according to the package directions. Allow to cool to room temperature (if you pour it on top of the set Jell-O while it's still hot, you'll melt the bottom layer). Once cooled, evenly divide the orange Jell-O among the 4 glasses. Place back in the fridge and allow to set for another 1 - 1½ hours.
Place a metal bowl in the freezer for 10 minutes. Remove the bowl and add the heavy cream, sugar, and vanilla extract. Whip until you form stiff peaks. Top the layered Jell-O with the whipped cream (I used a piping bag, but you can just spoon it on top) and place two eyes on top. Serve with candy corns and enjoy!
