The Brute X-Mosasaurus gives live birth after mating, skipping the egg-incubation step entirely. Gestation takes approximately 8 hours at default rates.

The baby Brute X-Mosasaurus takes approximately 7 days and 17 hours to fully mature at default rates - at a glacially slow pace - plan for a multi-day commitment. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.

Each baby inherits stats from both parents with a chance of mutation - +2 wild levels to a random stat plus a color change. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

Maturation has three phases: Baby (0–10%) lasts ~1111 min and requires constant hand-feeding. Juvenile (10–50%) spans ~74h - it can eat from a Trough now. Adolescent (50–100%) takes ~93h - continues eating from troughs, nearly fully grown.

Don't skip imprinting - each successful imprint boosts the Brute X-Mosasaurus's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

The raising calculator above shows exactly how much food you need for each maturation phase of the Brute X-Mosasaurus. Expect ~1111 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

The multiplier feature helps plan large-scale Brute X-Mosasaurus raises by totaling food across all babies. Different food types have different spoil timers - factor that into which food you stockpile.
