In Adopt Me, pets level up through 6 growth stages: Newborn, Junior, Pre-Teen, Teen, Post-Teen, and Full Grown. The task counts vary by rarity, with common pets reaching Full Grown faster than legendary pets.

  • Uncommon: Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown.
  • Rare: Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown.
  • Ultra-Rare: Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown.

New pets

If you meant the new event pets , one recent guide listed these Sugarfest pets: Candicorn, Cocoadile, Gumball Caterpillar, and Gummy Guana. That guide explains how to obtain them, but it does not give a separate level-by-level age chart for each of those new pets.

Pet type| Full growth stages| Tasks to Full Grown
---|---|---
Common 14| Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown 14| 20 tasks 14
Uncommon 14| Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown 14| 25 tasks 14
Rare 14| Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown 14| 50 tasks 14
Ultra-Rare 14| Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown 14| 58 tasks 14
Legendary 14| Newborn, Junior, Pre-Teen, Teen, Post-Teen, Full Grown 14| 62 tasks 14

TL;DR: all Adopt Me pets use the same 6 age stages, and the number of tasks needed depends on rarity rather than whether the pet is new.
