As places to play go, it looks like a rather prickly one.
But these baby dormice were clearly feeling up for a challenge especially when there was a juicy blackberry in sight.
The plucky trio were in fact lucky to be alive after being found orphaned.
The youngsters were rescued in the hamlet of Middlewood, on the edge of Bodmin Moor, Cornwall.
Geoff Brown heard their squeals coming from a beech hedge in his garden.
He called in his neighbour Jen Bousfield – who happens to monitor the endangered species – to investigate and she soon recognised the mice were in danger.
She found six orphans in total in the hedge, with their dead mother lying close by.
Soon after, Jen and her husband Peter drove the animals to Secret World, at Highbridge in Somerset.
Charity founder Pauline Kidner said that sadly one did not survive the two-and-a-quarter-hour journey and two others had died later – but the three survivors, were all doing well.
She said: "They are being fed on honeysuckle, blackberries and chopped nuts and if their weight reaches 40g before winter, then we will release them back into the wild, but if not then we'll look after them for release in the spring."
