One day, I thought of ways that can be used for creating a palindrome. So I decided that I will turn into a larger number by adding the reversed digits to the original number and keep doing it till I finally obtained a palindrome.

I live in a bowl. I can swim. I have a tail. I also have fins and big eyes. What am I?

I have an eye but still cannot see.

Who am I?

The happy one was crying and the sad ones were smiling.

What am I?
