Can't seem to find how to grab the other tins even after going to the garage view.
Thanks for playing, and sorry that wasn't clear! You can't pick containers in any order. They come one at a time, and the next one only unlocks once the one on your bench is completely finished. The garage view you open with G just shows the room until then, so clicking things in it won't do anything.
"Finished" means all of these:
- the coffee can is poured out (keep clicking it until nothing more comes out)
- nothing is left on the bench, including stray items in the corners
- the muffin tin cups are empty, if you've bought it (this is the one that catches people)
- any keepsake on the bench has been picked up
Once that's done, the garage view opens on its own. The next container glows with a "Next: …" tag, like the bucket in the screenshot. Click it, or click "Bring in the bucket".
If you've done all of that and it still won't unlock, tell me what's still on your bench and I'll look into it. That would be a bug.
