The event map is segmented into various areas, which can be unlocked by obtaining Coins, Keys, and Cards from the featured play spots.

World features

Exclusive Map: The Trading Packs world has taken the place of the Valentine’s Event 2025 map, bringing a fresh way to play Pet Simulator 99. At the center of the map is the area with the breakables, which grant Coins when smashed open using Pets.
Card Packs: The Coins acquired through breakables can be used to open four distinct card packs by default. Three of these are next to the breakables, while the fourth is found in the purple area, across the platformer course. New card packs can be unlocked as you progress through the different areas.
Pets: Pets based on the cards you acquire through pack openings are available, albeit in a non-standard way. This time, fuse three identical cards to get a pet of the same type. Use these pets to get bonus coins while breaking open the destructibles.
Upgrades: Upgrade various aspects of your pack opening experience to significantly enhance it. Upgrades can be purchased using Upgrade Cards, also acquired from pack openings.
Index: The card Index tracks your progress through the event. Completing this database is the main objective of the event. You can view your card collection through this menu as well, showcasing the different pet-themed collectibles you’ve acquired so far.
Collector Preston Quests: Complete pack-opening quests to receive exclusive cards. These card rewards are not available elsewhere, but they are tied to the event’s progression system. So, you will naturally complete them as you play through the world.
Merchants: Purchase various items and boosters at the Card Shop Merchant. Unlocking access to them requires you to obtain a key by registering 40 unique cards into the Index.
Evil Clan Battle: Trading Packs world comes with a faction battle as well, where the faction that pulls the rarest cards from packs scores more points and wins. Among the winners, the top scorers will be rewarded with exclusive Pets, medals, hoverboards, and more.
