When it's late and there's no Pokémon Center nearby, Dawn comes up with the solution: a visit to a nearby hot spring hotel, owned by the parents of her old friend Leona! Dawn and her friends arrive at the hotel ready for a relaxing soak in the springs, only to find Leona and her three Swinub in crisis mode because the spring water has stopped flowing. Now Leona is counting on her Swinub to use their superb sense of smell and sniff out another hot spring source.

With Dawn and her friends along to help, Leona follows the Swinub to the site of a new hot spring hotel. The construction workers are Team Rocket in disguise, and they claim to have found this spring water on their own. Leona notices the spring water here is just like the water back home, leading her to suspect they've been tapping into her hotel's pipeline. Right on cue, a Wooper shows up with the proof she needs to prove this "new" spring really is just the diverted water from her family's hot spring!

Team Rocket throws aside their disguises and unleashes a new robot, the Badabing Super Soaker Number Six. The robot is no match for Dawn and Leona's teamwork, and once Team Rocket is dealt with, the hot spring can start to flow again. But first, Dawn and Leona, using Piplup and Swinub, have a tag battle against Brock and Ash, who use Sudowoodo and Chimchar. After a frosty draw, everyone heads to the hot springs for a great soak to psych themselves up for the adventures ahead!
