It's time to take the King's shilling and head out to sea as this episode starts with naval tales as a walrus takes on a Russian navy boat, before Roddy grabs a calculator and does some truly bonkers marine mammal maths. Once the calculations are finished though, we take a look at how our activities at sea have impacted ecosystems in ways (perhaps, the naïve amongst us!) would never have thought...

That's not all of course, as we then head not to the arena - but a deviously constructed battle box for the fight segment against a crab, and then round things off by assembling our stag do teams (bachelor parties for those overseas!) from the natural world. 

As we near our hundredth episode and series finale, there's also a bonus clip from the Patreon too. Head over now and use code GOOSE for an extra 30% off your first month.
