Elizabeth's Yumee

Elizabeth's Yumee was the eighth Pokémon caught by Elizabeth Storybook in Alola.

History
Omnom was caught at the Ghost's Kingdom, a kingdom that worshipped Ghost type Pokémon and had a portal leading to a paradise for them. It first appeared alongside its mother, a Liscious, as a week old baby.

After she drove off Colonel Hansen, Liscious asked Elizabeth to take care of Omnom, and she caught it right in front of the portal.

It was a member of her party for a long time until Brionne is back, when it evolved into a Yumee and then told Elizabeth that its mother had passed away and it needed to take over her role as the kingdom's protector. Elizabeth respected it and Ditto's decision and released them to protect the kingdom and the Pokémon who lived there.

Personality and characteristics
As an Omnom, it was relatively childish and happy-go-lucky, and often spoke in baby talk. After evolving, it took on a much more serious personality, especially when it and Elizabeth said their final goodbyes.
