88 rockhopper on eBay....

[Spinsterboy]

I think it’s an ‘89. Rear mech, shifters & the booster on the u brake. A lot of bits have been changed though. Wheels for sure.

FWIW I have an earlier one with 24” wheels - pic in sig - and it’s a slightly different shade of blue.

I tried to find one for my daughter. They are like hen's teeth!
