Place this clip under the visual reveal itself, not over the build-up before it, then follow it with a short cartoon splash for a water exit and a brief audience laugh to close the gag in longer edits.
Über diesen Sound
This clip is about 13 seconds of walrus vocalisations, a loose run of deep barks, grunts and bellowing roars rather than a single short call. It feels funny and a little chaotic, the heaviness of the animal making every noise sound oversized and ungainly, which is why listeners reach for it when something big and clumsy enters the frame.
