>>85363037100% is probably 3/4ths the length of pikmin 4 IF she does a certain task offscreen. knowing fauna though, she'll turn that task into a zatsu, which means it might as well as be as long as 4. NOTE: I have slightly accounted for Fauna's lack of dandori, but given how bad Fauna is at pikmin, she may take even longer than Pikmin 4 would take. Certain late-game dungeons make me fearful for how many attempts they're going to take Fauna.
NOTE 2: I forgot that Fauna isn't save scumming. This series could be 50 parts long if she keeps that up.
