Trivia

• This is currently the second best Brainrot craftable in the Craft Machine. (And will stay that way as the crafting machine is gone)
• This Brainrot is a baby/los brainrot.
• In Spanish and Portuguese, Primos translates to "Cousins", but it's named "Los Primos" in-game due to being prime animals in the sea.
• This Brainrot profit is not that good, because it needs Los Bros (24m/s) , 67 (7.5m/s), Los Orcalitos (235k/s) and Los Tralaleritos (500k/s) being a final profit of 34.5m/s. But, for index and space, sometimes it can be worth it to craft.
• This was the last Brainrot Sammy added to the Craft Machine before it was removed.
• This Brainrot requires a 67 to craft, possibly referring to cousins usually being portrayed as the "brainrotted ones"
• This Brainrot is in the Aquatic Index and can be obtained via Fishing. IF the user is lucky enough because this is one of the top 5 rarest Brainrots to get from fishing.
