SCP-983 song (Birthday Monkey)

This is a mechanical monkey
Made around 1940
It holds a striking rod, and a bell
Siting here it has no containment cell
You may go closer, do not be afraid
On someone's birthday it will activate

Ring, ding, ring a ding, ding ding
It's your birthday!
Ring, ding, ring-a-ding
Ring ring ding ding, birthday!
Ring, ding, ring-a-ding, ding ding
It's your birthday!
Birthday!
Yeah, birthday!

It will stand up, do a backflip and then sing
When it's done, it will pause
Ring it's bell and rebegin
Take the candy that it drops no, do not neglect
You must reverse the effect

It's harmless, but can kill you
So you must know what you must do
And because it's your birthday
It keeps on singing all the way

Ring, ding, ring a ding, ding ding
It's your birthday!
Ring, ding, ring-a-ding
Ring ring ding ding, birthday!
Ring, ding, ring-a-ding, ding ding
It's your birthday!
Birthday!
Yeah, birthday!

It will stand up, do a backflip and then sing
When it's done, it will pause
Ring it's bell and rebegin
Take the candy that it drops no, do not neglect
You must reverse the effect
