A pair of mallards honked at it until it got out of the water, then it swam up the lake to this log, went inside, and then popped out of this hole. Observed with @micro_ecologist
Two big adults walking on top of the fence and roof. The second one almost got stuck in the redwood on the way up.
This was found with my friend’s apricots I think. Not sure if store bought or wild.
Update: Apparently it’s a spiked cucumber
