Hollowflight

Hollowpaw is a dark brown tabby tom with a pale, sleek-furred belly.

The Fourth Apprentice

 * Hollowpaw is a new RiverClan apprentice. His mentor is Reedwhisker.

Night Whispers

 * Hollowpaw is seen training with Ivypaw, his Clanmate Minnowtail, and several other cats in the Dark Forest by Hawkfrost. He saves Ivypaw when she is pinned on the riverbed by Darkstripe, and together they bowl him over in the water, humiliating him in front of Hawkfrost. Later he is heard but not seen by Dovepaw being scolded for putting thorns in a nest. The exact reason on his presence in the Dark Forest is unknown.

Sign of the Moon

 * Hawkfrost asks Ivypool to teach Hollowpaw some moves and he is now noticed as a new apprentice of the Dark Forest. Ivypool asks if this is Hollowpaw's first visit to the Dark Forest, but he says this is his second visit. He then tells her how he got there. Hawkfrost came to him after being bullied by Mossypaw, Rushtail, and Troutstream. He told him that he could stand up to them if he trained with them. Ivypool says they would, and then feels bad for the apprentice and then Ivypool teaches Hollowpaw a ThunderClan tactic move to fend off a fox if invading. He does it well, and Ivypool praises him. Hawkfrost also mentions Blossomfall as a new Dark Forest recruit as he did with Hollowpaw.
