Bálint SzilaksziSonix the hedgehog got one thing right, hedgehogs are comically fast compared to their body structure and they rack up serious distance at night.
Our pygmy hedgehog does something like 4-5km with his soundproofed wheel every night.
Their belly is super soft. Here is a picture from a while ago.
