This is not a baby seal you can just bash it's head into the sidewalk, if I recall correctly that's Neil the Seal who is young male elephant seal. This is for all intents and purposes a sea hippo with smaller jaws but with the bulk to match. You would need a decent rifle to put him down and not a lot of people would appreciate you shooting the local as well as internet celebrity seal dead in their neighbourhood, as gay as that may seem. It's safer for everyone to just relocate the fucker while being optically better for all people and agencies involved.
