It changes from game to game. Not only will each player find a distinct "heaviest" one (which could be different the next time you try) but you also have to weigh a certain number of pumpkins, either 6 or 7, before it will let you decide.
When you talk to Linus and Lucy, Lucy wants the "heaviest" pumpkin, so you will weigh the 7 of them to find which is heaviest. Then she will ask Linus to get one back to the house, which you do by rolling it (carefully) to the left, avoiding hazards.
Talk to Charlie Brown and Pigpen, then go right to the Pumpkin Patch where Linius is planning to meet the Great Pumpkin. Lucy needs a pumpkin for a jack o'lantern so she wants the heaviest one there. Weigh the 7 against each other to find the heaviest.
When you select the heaviest pumpkin in the pumpkin patch for Lucy, and roll it back to her house, Linus gives you his bag. (Take it to Pigpen outside.)

There is no pigeon on great pumpkin island.
The pumpkin patch is to the right on Great Pumpkin Island. It was the only area shown in the island preview.
She wants the "heaviest one", and you will have to weigh all of them against one another two at a time, keeping the heavier one each time. The actual pumpkin changes, and can be any of them.
You are looking for the "heaviest" and this changes each time you play. Basically, you have to weigh all 7 pumpkins, two at a time, keeping the heavier one each time.
There are no buildings or upper rooms on Great Pumpkin Island.
Not the largest but the heaviest. You have to weight them against each other, two at a time on the balance. Whichever one is heavier stays, and you bring another one up. Check all 7 from left to right to find the heaviest (which changes each time you play).
You have to quickly compare them two at a time : place two on the scale, and when the balance tips, keep the one that goes lower (heavier) and put a new one, the next in line, on the other end of the balance. Repeat this process for all 7 pumpkins, then lift the heaviest one to Lucy.
The name of the island is Great Pumpkin Island. See the related question below.
