Tartaragno

Tartaragno is a Common brainrot in Steal a Brainrot, generating $13/s at a cost of $1.5K — a payback time of about 115 seconds. For a Common, $13/s is toward the top of the tier, putting it on par with Pipi Kiwi and making it one of the stronger Common earners available. Its identity as a spider-turtle hybrid gives it a distinctive look that stands out among the more standard Common designs, though its income is what really makes it worth noting.

Tartaragno has been removed from the Red Carpet rotation and is now unobtainable through normal purchase. Your only paths to acquiring it are stealing one from another player's base or picking it up through trading. Because of its unobtainable status, it can carry some collector value beyond its raw income. If you do manage to get one, applying a Gold or Diamond mutation is the best way to maximize the return on a piece you likely worked for — at $13/s it is already strong for a Common, and a mutation pushes it further into genuinely useful territory.
