Quick video not professionally edited or anything but I just wanted to show the 4 different Pumpkaboo sizes and how you can tell them apart in Pokemon Sword and Shield. Pumpkaboo's HP and Speed base stats are affected by their size. The smallest size has the best Speed and lowest HP. HP gets added and speed is subtracted by 5 points for every size increase. The massive size has the best HP and lowest Speed. For more info, just go to https://bulbapedia.bulbagarden.net/wiki/Pumpkaboo_(Pok%C3%A9mon) Thanks!
