Pierce and Taylor are two anthropomorphic yams that guard the observatory. They only allow gourds to access this location. They only make a brief appearance in Pajama Sam 3: You Are What You Eat From Your Head To Your Feet.
Pierce and Taylor serve as guardians to the observatory. They will only allow gourds to access this location. To enter, Sam must wear a pumpkin (used as a hat) in order to get pass them. If Sam tries to get pass them without the pumpkin, they will prevent Sam from entering. If Sam tries to get pass them with the pumpkin, they will allow Sam to enter.
