When I was in I think it was 6th grade, which would have made it 1988, we had an assignment to write and present a report on an animal. Being a weird little kid, I wanted to pick a weird little animal. My first thought was "platypus", but while researching the platypus I learned about the echidna, and fell in love. After that, the echidna became My Animal. It was like this super special weird little guy that only I knew about.
In 1994, when Sonic the Hedgehog 3 introduced the character Knuckles the Echidna: that was the end of my private relationship with the animal. Now eeeeeveryone knew and was into the echidna! It was bittersweet for me. Of course, I wanted people to know about the echidna. Echidnas are awesome! But it could no longer be my special little secret animal. If I told anyone I was into echidnas now, they'd just assume I was a Sonic fanboy (not that there's anything wrong with that!)
