Having lunch outside always seems like a good idea until a Seagull tries to rob your sandwich.

For Dave's World, Dave brought us some random Seagull facts and he also plays a new tune that was devolved by food delivery company Deliveroo along with a Seagull expert to help deter them whenever you need to be left alone. It'll be very handy the next time you're having a picnic in the park.

Click Play above to hear the tune (it's kind of catchy).
