To get a Maw in My Singing Monsters, you need to breed two specific monsters:
Mammott (Water element)
Toe Jammer (Cold element)
Here's how to do it:
Step 1: Ensure you have a Breeding Structure on one of your islands. You can purchase it from the Structures menu for 200 Gold or 10 Shards once you reach Level 7.
Step 2: Open the Breeding Structure and select Mammott and Toe Jammer as the parents.
Step 3: Wait for the breeding process to complete. It takes 30 minutes to breed a Maw. You can skip the wait by spending 1 Diamond.
Step 4: Once the breeding is complete, tap on the Nursery to collect your new Maw and place it on any island126.
Rare Maw can be bred using the same combination but is only available during special events, taking 60 minutes to hatch or requiring 1 Diamond to speed up13. Epic Maw requires specific combinations and is available during seasonal events14.
