Omg I wasn't going to say so as not to dox myself, but you were so close that I can't not say: [STRETCH MONSTER](https://www.plaidstallions.com/kenner/sa/stretchmonster.html)!

[EDIT]: Also, you son of a bitch, how dare you localize me in time so accurately?

Can you put us out of our misery - what was this toy you spake of?

Stretch Armstrong?
Evel Knievel + bike?
Bionic Man action figure w interchangeable faces?
Tandy TRS-80 Color Computer?

Bitman

I remember as a kid, for xmas, I got this toy that I'd hungered for with all my heart for months.  It was the white-hot sun of joy.  It was so incredible to feel it.

And then it was incredible to feel, the next day, hedonic adaptation, the feeling of: now what?

Quite a 24 hours.  I still think about it.

What was the happiest day of your life?
