Here you go again. Click on the green plant to find a key in it. Use it to open the trash can. Click on the painting to see the numbers V II IV III VII. Put in 5 2 4 3 7 into the locked door on top of the shelf to get headphones. I got that much done on my own!
Click the bottom of the plant for a medal. Click on it again to obtain it and put the water on the painting. Click on the very lower part of the bookshelf to find the plug. Plug the computer in. That's enough for one medal which is good enough for me.
