Brownmouse has so many kits! MoonTail, DaisyPelt, ThrushRun, RedSnail, AntPounce (BrownMouse and WebStripe) JumpPool, SnipNight, CrabNeedle, OakMouse, MinnowBlink, PranceEars (BrownMouse and NightStar) StarlingStrike, BuzzardBlaze, AspenLight, Dusksong (GrouseMane with BrownMouse as surrogate) AngelfishTooth, FidgetGills, TetraTrail, BlueSpore (CreatureFall and GoldfishFur with BrownMouse as surrogate) - @wills-woodland-warriors
Making me think about their relationship with each other, particularly Minnowblink, Pranceears, and Grouse's litter, since they hung out a lot.
Maybe one of them noticed that Pheasentpaw (very close to warrior-age) had a crush on the recently-named Buzzardblaze, and talked him up. They now have kits together, so safe to say it worked.
