Netmarble has kicked off a pre-100-day event for its mobile idle RPG, Stone Age: Grow Up, and has also introduced a new pet, 'Kinggor'.

A 100-day celebration push event will run until June 18th. By logging in and claiming push rewards, players can snag up to 44,000 of the game's core currency, 'Blue Gems'.

Seven commemorative coupon codes are also on the table. Inputting these codes, which will be revealed until June 18th, grants players 9,000 Blue Gems, 700 regular pet summon tickets, 500 capture tickets, and 500 acceleration tickets.

The new pickup pet, 'Kinggor,' has also been added. This water-element, close-range pet charges at the furthest enemy within its range, aiming to shatter the enemy formation and create strategic variables. It also heals itself as it engages in combat, growing stronger over time. Kinggor will first appear on servers with a common schedule applied, and will be sequentially added to newly opened servers.
