This is Sonic. Sonic the Hedgehog.
He’s a baby hedgehog I found last summer in my garden.
Sonic is living a dangerous life because I have a robot lawn mower, and the robot does not care about hedgehogs at all.
Luckily, the little fella’ seems to not live near my garden. I haven’t seen it since that day. And for its own safety, I hope I will not see it again.
