According to animator Steve Wolfhard
on his Twitter account in his original script for this episode that were one of the original scripts to the episode. There was going another epilogue in where Jake becomes an old dog and dies. Then his funeral is at the candy kingdom where Princess Bubblegum, Marceline, BMO, Sweet Pea as a teenager, Mr. Pig, Treetrunks, Lady Rainicorn, Jake and Rainicorn's kids and grandchildren and some candy citizens appear for his funeral while his body becomes big and uncontrollable that cause the guests to get out unharmed while the candy kingdom is destroyed from it. Latter Princess Bubblegum in a ship grabs Jake's really big body and puts it in the ocean where it drifts to the missing chunk of the earth from the Mushroom War where it fills that entire chuck and years latter becomes a new continent for earth. However the heads of Cartoon Network decided not to put it in the final print of the episode and found that it would be better if the viewers would think what their own thoughts of what Finn and Jake's futures will be like to them.
