Pet Duck

An odd dream I must say...

I had a large fish tank. It had fish and a few frogs in it.
I watched as a small frog ate some fish. Then a larger frog ate the smaller frog... all in one gulp. Then out of no where a small off white duck (not fuzzy, but not full grown)came from the corner and gulped up the large frog.
I scooped the duck out of the tank and into my arms. I carried him around and called him "Toodles"
He was my new pet. I carried all over the place. Then I took him to a park. The park was on a hill and had a concrete drainage ditch running down the side. There was a structure to the right, the drainage ditch all along the hill, and to the left, open grass with some trees. Straight ahead was the bulk of the park to the right and left... with a stream and everything. I had in mind to let Toodles swim in the stream.
We walked down the hill to the right of the drainage ditch, then at the bottom, where the stream started, I let Toodles go.
Almost immediately he got pulled by a current over to a storm drain where the ditch went under a ledge and the stream started on the other side. I panicked. I ran and knelt down and put my hands under the ledge trying to free him from the drain.
Then I woke up.

ummm yeah... I have no clue.
