The spikes on the forest floor

On the village's ground floor, a pit of sharp spikes cuts the path in two. Walking into it costs a life.
Nudge 1Where to look
Dizzy can't jump that far. Something to cover the pit with would do.
Nudge 2A stronger push
On the first floor, not far from Dizzy's hut, lies something long, flat and strong.
Show the solutionThe whole answer, with a video
Pick up the large strong plank of wood on the first floor (left of Dizzy's hut) and carry it down to the ground floor. Stand just before the spikes and drop it (B): it lies across the pit and Dizzy walks over it.
Why it works
The plank's use routine checks that it's dropped where the pit is; then the spikes' cells become a floor, and the plank is drawn over them for good.
