Lost....

In the forest at the island Terschelling I saw this, hanging in a tree.

We left home this morning with the sun fully shining... Now we are here and it's grey and ccccold...
We are here to wake up our mobile home after the hibernation.
First thing tomorrowmorning is trying to repair the thermostatic tap in the bathroom because only cold water is coming out; when I turn to "temperature rise" the flow almost stops...

Here is the teat in LARGE....
