I propose we place a limit on corral carrying capacity. The standard corral being able to hold 6 slimes (Largos counting as 2) and upgrading by 3 with every upgrade. Upgrades are 250 coins and there a total of 8, maxing out your corral at a capacity of 30 slimes. Let me know what you think!

Alternative: Start with 5 and get 5 for every upgrade, meaning you start off one less but it only costs 5 upgrades instead of 8.
