Episode 4: Dig Dug and Mappy Are Friends

In the episode Dig Dug and Mappy Are Friends, Dig Dug convinces Mappy to take a day off work and go on a road trip to see a Wonder Momo(Namco wiki) concert together. Goro doesn't show up to the company building that day, which is was convinces Mappy to go along with Dig Dug.

During their way to the concert in Bandai City (another play on the Bandai Namco company name), Mappy's car pops a tire and breaks down, leaving them both stranded on the roadside of a desert, too far away from any city or town to walk. They lay in the heat in misery, before getting the idea to find a Pooka (Namco wiki) to replace the tire, as they are round and apparently everywhere due to an infestation, being very easy to find.

They then get back on the road and make their way to the show, only to find they missed it and were too late. They run into Goro much to their surprise, who also seems to be a big fan of Wonder Momo, and they all agree to pretend that they didn't see each other there.
