I think a part of us can relate to Tingle.
The part that never wants to grow up,
the part that feels disenchanted with the reality of life.
There's a lot of rage directed towards Tingle.
I wouldn't mind if he continued to appear in the games.
He represents a direct link from the real world to the Zelda universe.

Granted, not all of us will be wearing green full-body spandex in our 30s.

But still,
it's a thought.
