Does anybody know what Lego set this is from?

I’ve long since lost the instructions, but not my Lego collection. I probably built it 25+ years ago (I’m 37) and it’s been broken and repaired so many times it’s drifting from its original design. I’d like to fix that.

I have this green baseplate and I am afraid of cracking on minifigures what do i do?

I got this tub at a garage sale. Can you see any sets I could pick out and build off the top of your head? About half of them are visible in this photo.

A friend said these look like a mostly late-2000s to early-2010s collection, at a glance. I know this might be kind of a dumb question, but I'm not the kid I used to be back when I would've spent hours and hours just experimenting with a heap like this. I'm getting old I think... Can you help me?
