While the Brave Olivine has its computer system rebooted, it’s picnic time for the crew!

Strange things are happening aboard the Brave Olivine - could a Pokémon be the cause?

The Rising Volt Tacklers answer a request from an archeologist acquaintance of Friede's to move some rocks at an archeological dig and head for the dig site. However, they have difficulties getting started with the work, as ferocious Waruvile and Waruvial seem to be interfering. Liko, Roy and Friede set off to investigate inside the ruins to get to the bottom of this.

The Rising Volt Tacklers are visiting a beach in the Paldea region. Liko and Roy are having a great time playing with the local sea Pokémon, but trouble suddenly arises when Hogator gets washed out to sea! The day ends up getting saved by Irukaman, the Hero of the Sea! Roy is amazed at how cool Irukaman is... but just then, someone is lurking nearby, planning to catch Irukaman's supposedly never-before-seen transformation scene on camera...?

Only 30 boxes of the famous treat "Sea Digdaman" are sold every day, and you have to stand in line for them too. However, as a thank you for helping the store manager, Liko and Roy are given some even without having to stand in line. A certain person from the Explorers was standing in line for the treats as well, though... and as they're on their way back to the Brave Asagi, Roy notices a letter of challenge that has been stuck to Hogator's back...?!
