Nawin receives some nice souvenirs at his farewell party, and he and Nico and Lisa discuss various German cities.

Nico and Lisa eat pizza with Lisa's roommates and talk about the party they are having.

Piggeldy is curious about birdsong, and Frederick has a few questions he wants to answer for himself as well.

Nico and his friends order pizza and find out that someone has responded to the photograph of his aunt's bicycle shop on social media.

Frederick tells Piggeldy that he can fly down a mountain by flapping his ears.

When Nico shows Nina and Sebastian the photo of his aunt, Sebastian has the idea to post the photo online and see if anyone recognizes the bicycle shop.

Piggeldy tries to learn how to drive, but something doesn't seem to be working out quite right...

Nico goes to the "Wohngemeinschaft" ("WG") where Lisa lives and meets her housemates, who are getting ready for a party.

Piggeldy and Frederick go hiking, which doesn't appeal to Piggeldy at all until Frederick starts a sing-a-long.

Nico and Lisa go to the police station, where her father files the little information Nico can give him.

Nico has the bold idea to call a radio station and tell them about his missing bag.

While Lisa drops Emma off at a birthday party, Nico waits in the car and hears something interesting on the radio.

Nico and Emma play a game in the car just before Lisa drops her off at a birthday party.

Lisa calls her father, a policeman, to see if he can help find Nico's aunt.

Piggeldy learns to read... sort of.
