WHO HAS FLOATIES AND AUTO PLAY?

GUYS I REALLY NEED HELP.
I NEED TO KNOW HOW TO PUT A FLOATIE CORRECTLY AND WHAT SITES TO USE.

I can already put in videos that you have to click for them to start playing, but I really want Touch You from YBC to start playing when you open my profile (aka just auto play) please!!

and I also wanna put Yui and Yuri floaties in my profile but i've tried and absolutely NONE work. along with finding no sites that work! 

this is something I would like to be replied to quickly on, so if you code yourself or if you have floaties or autoplay on your layout and you know what sites to use, please do not be afraid to TELL ME. it would help so much!! thank youuu <3
