Doki can't stand when he doesn't know something. So when Gabi becomes extrasecretive
about her diary, he's determined to find out why. What's Gabi hiding? To find out, Doki, Mundi and Anabella fly off to a friend's Junior Spy Lair, to learn about spy techniques, and ways to uncover secrets that others don't want you to know! They share what they learn with 'Sneak-ret' Agent Fico and his spy-gear provider Oto, who are doing their best to get a look at Gabi's locked diary. But the kids begin to wonder if invading their friend's privacy is the right thing to do, and in the end they race home to call off the mission.
Team Doki is eager to meet their friend Emma's pet monarch butterfly. But the Team
has barely landed in Emma's Michigan, USA town, when 'Augustine' flutters away,
heading south! Anabella imagines she's going to a beautiful 'butterfly city'. Emma hopes
that's true. Doki isn't convinced, but where do monarchs go for the winter? They decide
to find out, by following Augustine! In a high-flying expedition, the Team follows the monarchs on their journey, helping out as the butterflies face predators, soar over mountains, and find food in deserts as they wing to their destination in Angangueo, Mexico. To the Team's delight, Augustine's winter home truly is a 'butterfly city'!
