The floor ended up covered in bits of old wallpaper (good job they had covered the carpet) - some very long bits, but lots and lots of little bits too. And the pieces were still a little bit sticky from the old glue.
Boo thought it was great fun to pretend that all the paper bits on the floor were like the leaves which fall from the trees in Autumn, and he spent lots of time kicking through them, and making the mess even worse.
When they had finished playing, though, Boo started to gather up all the bits of paper together to put them into rubbish sacks for the dustman to collect. He ended up with more bits of paper stuck to him than were in the bags!!
In the end, all the bears helped him tidy up all the bits, even those which had ended up in the windowsill, and behind the radiator (a good job for tiny Tommy) and in Scary's waistcoat pocket (how had they got there, the bears wondered??!?)
