Donating to the museum[edit]

In New Leaf[edit]

After the Giant Isopod is donated to the museum, it can be found in the small tank in the middle in the first room of the sea exhibit.

"Giant isopods are related to the pill bugs, and they can grow up to 20 inches long. They are scary looking but still come across as humorous for some odd reason. Despite their roly-poly builds, they are surprisingly fast swimmers, making them rather agile. They have big appetites, gaining the title 'sea cleaners' mostly because they eat dead fish on the sea floor."

In New Horizons[edit]

When donating to the museum, Blathers will say the following:

"Growing up to neatly 20 inches, the sea-dwelling giant isopod is the world's largest cousin of the pill bug. Twenty inches?! Twenty times as revolting, I say! Making matters worse for those of us who find the pill bug repulsive rather than "cute"... The giant isopod can swim shockingly fast and is known for its voracious appetite. In fact, it's most happy when dining on the carcasses of animals that have sunk to the bottom of the sea! This behavior has earned it a nickname..."the vacuum cleaner of the deep." Why must nature play such awful pranks on me?"
