Why was the letter C named after a big blue wobbly thing that mermaids live in?

It wasn't. It was a tiny misunderstanding.

They couldn't decide so they deferred from making a decision and put it to the side for a while.. then at last someone asked about the cside

Because the letter follows B.

In order to avoid getting stung by a B, people dive into the C.

Clerical error

Why was the letter D named after penis? 🤔
