Energetic pupils took part in a sponsored bounce to raise funds for Asfordby Captains Close Primary School.
Children were each given one minute to bounce as many times as possible on Friday.
Jo Smith, chair of the Friends of Asfordby Captains Close, said: “They all had a great time - we even managed to get the teacher to have a go!
“All for Fun Inflatables very kindly provided the castle for the morning. We’re hoping to raise in the region of £600 for the school.”
