Quick answer
What to do first
The official Roblox description confirms that players can use gear to destroy and enter other players’ bases, then steal pets. It does not publish an exact steal method, a best target, a cooldown, or a guaranteed outcome.
For Build a Base and Steal stealing tips, protect the pets you do not want to expose before taking a raid risk. The official loop supports building for protection and stealing pets from rival bases; this guide does not invent a fastest route, a base layout, or success odds.
