Does anybody find this strange?

In Skyward Sword, there was the loftwings you fly which are similar to the Fluzzards in Super Mario Galaxy 2. In Super Mario Galaxy 2, there is a boss named Gobblegut similar to Volvagia in Ocarina of Time. In Ocarina of Time, you see a portrait of Mario, Peach, Luigi, and Bowser from Super Mario 64 inside a window in Princess Zelda's chamber.

So:

Skyward Sword --> Super Mario Galaxy 2  --> Ocarina of Time  --> Super Mario 64

I SEE WHAT NINTENDO DID THERE!
