Innocence

"Mother, why is the small fire creature sick?"

I know that a darumaka is resistant to ice but how many baby creatures can survive without their parents in a frozen tundra, so don't go saying it don't make sense. It doesn't make sense to Vivi because he's only a child here, he's smart enough to know that fire types are resistant to cold so he's confused.

This is just a random thing, I think he's five here. During his travels with his family, they went all sorts of places. This place is pokemon version Russia, wherever that may be.
