- "This looks like a job for the Ice Climbers!"
- — Garchomp, before the Ice Climbers arrive, after Xiaoyu falls asleep.
Popo and Nana, better known together as the Ice Climbers, are small, young children. They both wield wooden mallets, which they use to whack enemies and break ice cubes. Both of them wear parkas; Popo's parka is blue while Nana's is pink. They can also be identified by the patch of hair exposed from their hoods. They are one of Garchomp's close friends.
Neither Popo nor Nana can help their sleeping. This leads to when they get tired, they fall asleep and start snoring. Evil-Man becomes really mad when this happens.
Both Popo and Nana are voiced by Hynden Walch. Hynden Walch would later be Talim's voice actress in the following Rocko franchise television shows.
