廣
This character, whose basic meaning was a shelter (it is a picture of a lean-to structure), appears in quite a few characters, usually as an enclosure. On its own, however, the character nowadays means “broad”. (Notice how “broad” also appears in the story).
[广大 (47) guǎngdà vast; extreme]
[广告 (138) guǎnggào advertisement]

/ (At the Formula 1 team’s secret test track) They have to build a shelter for the spare wheels and other equipment, broad enough to accommodate the ghostly teddy and his gang (who guard it all).
