He is on a borderpatrol with Appledusk and Eeltail. Appledusk sees Mapleshade struggling in the river and he jumps in to save her. Splashfoot sees the she-cat and he asks Eeltail what a ThunderClan cat was doing in the river. When Eeltail asks Splashfoot if the she-cat is Mapleshade, Splashfoot thinks that she is indeed the cat who fell into the river. After Mapleshade is dragged to the shore, she explains that her kits fell into the river while she was carrying them across the river. Splashfoot races after Eeltail as she exclaims that her kits are going to be in big trouble. After the two warriors take the kits out of the river, Eeltail and Splashfoot are seen standing over three small dark shapes: Larchkit, Patchkit, and Petalkit. Splashfoot, Eeltail, and Appledusk carry the dead kits to the camp.
After Appledusk confesses to Darkstar that he is the father to the kits, Splashfoot appears again when Darkstar orders Rainfall to help Splashfoot and Eeltail bury the kits.
