Age 75

Age 75 is the top-end Robux age item, not a pet you hatch — it sits in the catalogue with the Robux logo for an icon and carries no rarity, no egg source, and no hatch percentage. It contributes no passive itself; its sole purpose is to crank a chosen pet's age all the way to the 75 tier, the highest of this set, where that pet's real ability is effectively maxed out.

This is the whale tier of age investment. With abilities scaling on age, a pet at 75 hits its strongest practical output — the shortest cooldowns, the largest sell multipliers, the most frequent mutation procs available to it. The trade-off is brutal efficiency: the jump from 60 to 75 costs the most Robux for the smallest proportional gain of any bracket, so you pay a premium purely to top off the final stretch.

For a serious team this is justifiable on exactly one pet — your single most valuable, permanently slotted companion, and nothing else. Anyone buying Age 75 across multiple pets is burning currency. Realistically only veterans chasing a fully optimised flagship farm should consider it; everyone else gains far more by spreading resources elsewhere.
