Eeveelutions Pack

Habits and behavior
They are extremely social and cooperative, more like a playful wolf pack than a traditional wild pack. They have a soft hierarchy based on experience, not strength:
Social structure:
Younger Eevee follow a "mentor" of their preferred type (an Eevee that plays a lot with water often ends up becoming a Vaporeon apprentice).
Espeon and Sylveon act as "emotional guides": they detect problems and calm fights with psychic powers or calming tapes.
The Umbreon are the night sentinels; the Jolteon, day scouts.
Daily activities:
Tomorrow: Team hunting. Jolteon and Flareon corner fast prey, Vaporeon drag them into the water, and Leafeon trap them with vines. Eevee learn by observing.
Midday: Mass nap in the sun or in caves. They all huddle together forming a mountain of multicolored fur (the Glaceon cool the nest in summer, the Flareon warm it in winter).
Afternoon: "Evolution class." The Eevee play with evolution stones exposed to the sun, near water, or in cool areas to decide their future. The adults never force them; they only guide them.
Night: The Umbreon lead patrols. The Sylveon tell "stories" by projecting illusions with their ribbons.
Special habits:
Group baths: each type has its own ritual. Vaporeon and Glaceon in the river, Leafeon in mud puddles, Jolteon shake off electricity to dry quickly.
Games: They love "turn-taking." One Eevee hides, and all the others search for it using their powers. Whoever finds it first wins "mentorship."
Seasonal migration: they move between forest, mountain and lake according to the season so that all types feel comfortable (they never abandon any member).
Defense: When there is danger (a large predator or trainer), they form a circle with the Eevee in the center.

Composition
A typical herd consists of 12 to 20 individuals, divided as follows:
6-10 Eevee (the core and "pups" of the pack). They are the majority because they have not yet evolved and represent the future generation.
1-2 of each Eeveelution (generally one pair per type to maintain balance):
Vaporeon (aquatic)
Jolteon (electric)
Flareon (fire)
Espeon (psychic)
Umbreon (sinister)
Leafeon (plant)
Glaceon (ice)

General appearance
Seen from afar, they look like an explosion of soft colors and fluffy fur moving among the trees. They all share Eevee's elegant, fox-cat silhouette (enormous ears, large, expressive eyes, bushy tail), but each evolution adds its own unique touch:
Eevee are the most uniform: light brown fur with a fluffy white collar and blue eyes. They're always disheveled, with leaves or dirt stuck to them.
Vaporeon: Bright blue, jelly-like skin, dorsal fin and gills that sparkle in the sun. It appears almost translucent near water.
Jolteon: Electric yellow fur that sparkles like lightning, sharp eyes, and a spiked collar. It looks like a walking ball of static electricity.
Flareon: Flaming red mane and a tail like a torch. Its fur gives off heat even from a distance.
Espeon: Soft lilac fur, red jewel on its forehead that glows when it uses its powers. Elegant forked tail.
Umbreon: Jet black with golden rings that glow in the dark. Intense red eyes.
Leafeon: mossy green with leaves growing from its body (it looks like a living bush).
Glaceon: Crystalline ice-blue fur, crystal tips that jingle when walking.
Sylveon: Pastel pink fur with bows and ribbons that float as if they have a life of their own. The most "adorable" of the group.

Adult Pokémon can speak like humans, but pups only repeat basic words like "milk" or "hungry" or Pokémon names.
