Pokemon The Movie 03: Spell Of The Unown

Mii Snowdon is left alone after her father disappears while investigating the Unown, a group of letter-shaped Pokémon. While searching for clues, she discovers a box with tiles that may hold the key to her father's disappearance. Mii's only lead is a mysterious box containing several tiles, which she uses to make a wish to see her father again, inadvertently awakening the Unown. This causes the lion-like Pokémon Entei to summon itself as her father.
