Sing to the tune of The Farmer in the Dell: 

 

                C 
                The pumpkins on the vine,

                The pumpkins on the vine,

                Growing in the farmer's field,
                C     G7                       C
                The pumpkins on the vine.

                C
                We start out very small,

                We start out very small,

                Growing in the farmer's field,
                C     G7                  C
                We start out very small.

                C
                At first we all are green,

                At first we all are green,

                Growing in the farmer's field,
                C   G7                   C
                At first we all are green

                C
                We're orange when we are ripe,

                We're orange when we are ripe,

                Growing in the farmer's field,
                C         G7                            C
                We're orange when we are ripe.

                C
                We all are different shapes,

                We all are different shapes,

                Growing in the farmer's field,
                C     G7                     C
                We all are different shapes.
