My Grass-type starter for a Prehistory inspired region

Eleafant, the Tree Trunk Pokemon (Grass-type)

• "It makes all kinds of loud trumpeting noises with its trunk, these sounds can be heard from many miles away."

Eleaflute, the Woodwind Pokemon (Grass-type)

• "Its trunk helps it sing different kinds of songs. Their voices can vary from low-pitched to high-pitched, similar to human singers."

Eleaflinth, the Woodwind Pokemon (Grass/Rock type)

• "A skilled musician, its songs are said to have a haunting melody. The rock horns on its torso can blare out noises that can make the ground shake."

What do you think? Do you have any ideas for Signature Moves or Hidden Abilities?
