Pottermore moment: Chamber of Secrets, The Enormous Green Eyes

Continuing to the second moment in Chamber of Secrets: The Enormous Green Eyes.

This is what you'll see:

There is nothing here so zoom in.

Zoom in:

Hover over the door and it will open. Hover over the lawn mower and it will be switched on. A pair of sheers which you can collect. The stick in the paint can will move when hovered and there is a spider next to it which will crawl when you hover over it. Oh and I cut out the bicycle by mistake but in this zoom when you hover over the bicycle bell it will jingle.

Zoom in again:

In the wheel barrow you will find Dried Nettles to be collected and above that Rose Thorns to be collected.  Then in the bushes (left red circle) when you hover a pair of green eyes will appear.

And that is all! You will get a full bar.
