Om Android you can clear the cash of app somehow, but on iPad it turns out to be a problem... I couldn't find the cash of any app, but deleting the app really free up the space on your device. Then you reload it again from the cloud, and all images (dragons, decorations, habitats, buildings etc.) are loading anew, taking their place. But in the end it will take less space than before deleting.
