Well, I want conclude very least first day but fine if we skip the rest to the exams. Just want Yoshi have decent attempt to collect intel on 'other' teams besides his own during the week downtime (nothing like sneaking or breaking to rooms but more observe and spy others from distance if possible and listen rumor gossips of other teams). He would avoid spill anything about his surname, which gets revealed anyways on exams but he wants enjoy bit quiet lack of fame slapped on him because of his famous family name (ofc Konoha folk ID him by default and may perhaps spread word around).
