In Fisch , you don’t catch a “baby mossmonster” by normal fishing. Based on current community guides, you usually need to trigger the specific spawn/event for the creature, then fish in the correct area with the right bait and setup.

What to do

  • Go to the correct area for the Mossjaw/Mosslurker-type creature, depending on which one you meant.
  • Make sure the required event or unlock condition is active first, because some variants only appear during a hunt or after unlocking a hidden area.
  • Use the recommended bait and a strong rod with good luck/resilience so you can actually finish the catch.
  • If the creature has a strong progress penalty, expect a tough reel-in and stay patient.

If you meant Mossjaw

The most relevant guide says Mossjaw is caught at the Mossjaw Rest in the Forgotten Temple, after opening the area with the rune puzzle sequence, and it prefers Glowworm bait at night. That guide also says the secret Elder Mossjaw can appear there too, if you’re lucky.

If you meant Mosslurker

Another guide says Mosslurker comes from the Apex Fish Hunt event, with the pool spawning on a timer, and recommends luck boosts plus Shark Head bait, Aurora, and a high-luck rod. That makes it more event-driven than location- driven.

Fastest practical answer

If your goal is just the catch, your best move is:

  1. Confirm which creature you mean: Mossjaw, Mosslurker, or another “baby” variant.
  2. Go to its event or hidden spawn area.
  3. Use the bait the guide recommends.
  4. Stack luck/resilience boosts before casting.

The phrase “baby mossmonster” doesn’t match the main guide names exactly, so the safest interpretation is that you mean Mossjaw or Mosslurker.
