Pokemon Legends: Arceus added ancient evolutions for Pokemon we've known for years, including Ursaring. Naturally, that also means evolution items for these evolved forms. Thanks to the Peat Block, Ursaring can evolve into an Ursaluna. Sure, you get a companion Ursaluna for treasure hunting, but it's not quite the same as a battle buddy that fulfills a Pokedex entry.

Ursaluna has the word «luna» in its name for a reason. Ursaring can only evolve into Ursaluna at nighttime. However, a setting sun isn't enough. It also has to be a full moon.

It's easier to see the moon during a clear night sky or from a higher point of the map.

If it's not a full moon, don't worry. Talk to the Galaxy Team attendant at your base camp and repeatedly ask to «rest until nightfall» to move time forward. Unfortunately, the only way to
