Carl's trap-detection skill, which fires for the very first time — an instant too late — on the fire-ant suitcase.
Find Traps is a skill Carl didn't know he had until it activates for the first time as he unzips Princess-Donut's number-eight reward suitcase, flashing an unfamiliar warning — 'YOU SURE YOU WANNA DO THAT, BUCKO?' It surprises him enough to pause, but too late: the Literal-Fire-Ants are already pouring out. Only afterward does he realize what the notification was. It marks the skill breaking its 'level 1' threshold, meaning it should improve with use.
A newly-surfaced trap-detection skill of Carl's, debuting a beat too late.
