Bradley and Barney continue their European adventure in Germany. They head to the city of Frankfurt, where Brad is pushed to the edge, literally, as he attempts to abseil down the side of a building, facing forwards. The boys also make a stop at a bratwurst-themed hotel and soak up some local Bavarian culture when they have a go at finger wrestling. The pair finish off their time in Germany with a wet and wild adventure in the mountains.

The father and son have reached Slovenia, a country that loves its sport.

Brad's passion for bikes gives Barney an excuse to take his dad motocross racing, which turns out to be a very slippery challenge.

After hearing that one in 200 people in Slovenia is a beekeeper, they make a stop to meet one, but they won't be seeing any bees. Instead, they will be treated to some unusual honey therapies.

Upon reaching the capital city of Ljubljana, things take a magical turn when the pair join Slovenia's national Quidditch team, followed by a trip towards the mountains in Planica, where they have a go at the notoriously dangerous sport of ski jumping. Their stay in Slovenia ends with a visit to one of the country's most spectacular caves.
