The costume's passive ability is the same as Vacationer's, but the duration of the power-up can be longer after a certain upgrade.
Its upgrades don't follow the old pattern that gave multiple values of the first level's percentage, according to which the upgrades should have been 250%-500%-750% and so on. There's a number of costumes that don't follow that pattern either.
Its 'older brother' costume that gives more seconds while using the Banana Vaccum, Coder has a steady percentage 300% from the first level. This shows that Gameloft don't particularly like keeping a standard norm for all costume abilities, making every new costume unpredictable to guess its future upgrade levels unless upgrading them to level 2 or 3, in which case the pattern for higher upgrades becomes more clear.
