Who are the kits that ShadowClan had stolen from ThunderClan in Into the Wild?

Oh, dude, in "Into the Wild," ShadowClan stole ThunderClan's kits, Mistykit and Stonekit. Like, those sneaky ShadowClan cats just couldn't resist causing drama in the forest. So yeah, Mistykit and Stonekit got caught up in all that clan rivalry and had to be rescued.
