Things you didn't notice before in Mario games

The devs weren't kidding when they said that they were taking cues from Sunshine and 64.
 
It took me seventeen years to realize there's a racoon tail and ears on the shadow behind the number 3 on Super Mario Bros. 3's title screen.
 
Is the area that leads to Over the Rainbows (and how you fall into the moat if you fall off the level) actually the toilets of Peach's Castle?

I only noticed the other day that Jimmy T.'s moustache is a pair of musical notes- I just thought it was in the same range of strange moustache shapes as Wario and Waluigi. I also recently found out that when Donkey Kong falls asleep in Super Smash Bros. for Wii U he sucks his thumb, and that the part of the Mario Kart 7 Bowser's Castle music just before the track loops has the same tune as part of the Mario Kart: Double Dash!! Bowser's Castle's music.
 
Apparently there is a way to escape Chuckya's grasp in Super Mario 64, which is by tilting the control stick and pressing A enough times to make it drop Mario. Not sure if Super Mario 64 DS retained this functionality.

Thank you for reading.

He does this in Melee and Barlw as well. :)
 
Yeah, it's a slip.

Donkey Kong in Smash 64 makes these weird snoring noises that Mario happens to make as well. His animation is just as if he broke his shield.
