Reindeer

The Reindeer is a limited legendary pet tied specifically to the second part of the Christmas Harvest Event, hatched from the seasonal Christmas Egg. That "limited" tag is the headline: once the event window closed, the egg stopped appearing, so the only way to add one now is through trades with players who banked them during the holiday.

What makes the Reindeer genuinely interesting is its upgrade path rather than its base stats. Eight age-100 Reindeers can be fused into the Red-Nosed Reindeer using the Sleigh, which turns this from a one-off festive pet into a long-term project. That mechanic is why veterans hoarded extras instead of selling: the conversion demands both quantity and patient aging, so the floor price of a Reindeer is propped up by everyone chasing that fusion goal.

For value, judge it on intent. If you simply want a legendary holiday collectible, a single aged Reindeer is a clean display piece. If you are gunning for the Red-Nosed payoff, you are committing to eight fully grown copies, which is a serious investment of either time during the event or Sheckles and trade goods after it.
