Cherubi

Diamond: The small ball holds the nutrients needed for evolution. Apparently, it is very sweet and tasty.

Pearl +2: Sunlight colors it red. When the small ball is drained of nutrients, it shrivels to herald evolution.

Platinum: The small ball is not only filled with nutrients, it is also tasty. STARLY try to peck it off.

HeartGold +3: It evolves by sucking the energy out of the small ball where it had been storing nutrients.

Black +3: The small ball is not only filled with nutrients, it is also tasty. Starly try to peck it off.

Sword: It nimbly dashes about to avoid getting pecked by bird Pokémon that would love to make off with its small, nutrient-rich storage ball.

Shield: The deeper a Cherubi’s red, the more nutrients it has stockpiled in its body. And the sweeter and tastier its small ball!

Legends: Arceus: Once the fruit growing alongside the main body is large and plump, Cherubi will use the nutrients within to evolve. The fruit then detaches, becoming nourishment for other creatures.
