Coming from the 12th tier of the Halloween Event 2018 Main Event, the Red Pumpkin hasn't been obtainable since that event closed, so the only way in is through trading. Collectors of older Halloween pets still pick it up, often alongside things like Zombified (2019) or Bat (2022), but don't expect it to move fast.
Red Pumpkin (2018) is a Common pet in Murder Mystery 2. Its combined value is 123, #4 of 335 common items and #144 of 921 valued items overall. Demand is low: it sits in inventories for a while, and buyers often ask for a discount.
Closest in value: Bat (2022) (123), Dungeon (123), Zombified (2019) (123). Use them as a benchmark for a fair one-for-one trade.
