Who put bubble bath in the stream?

We have had so much rain over night that our wee stream has grown into a raging torrent and all that water tumbling over the small waterfalls has produced this heap of foam. I had to drive down to Craignure in the morning to collect a delivery and found all the water pouring off the hills quite awesome.
Back in the garden, I found a heap of frog spawn on the bank surrounding the pond (extra). At first I thought that a frog had been desperate to get rid of its load and hadn’t quite made it to the pond. On closer inspection, however, it looks like we might have had a visiting otter which has been  snacking on the contents of the pond that appeal to it. Time to put the spy camera out!
