After players donate a Whale Shark to Blathers, it will appear in the section for fish and sea creatures, specifically in the large tank in the north-eastern room. The exhibit has this to say about the whale shark:

"Whale sharks are the world's largest fish, but they're surprisingly some of the gentlest. They can swim at only three mph, so although they're large and very imposing, they're not really a threat. They swim with their mouths open to swallow vast quantities of tiny creatures and seawater. As they expel the water through their gills, they will eat what then remains. Since they don't have to bite prey, their teeth are file-like and number about 10,000 in multiple rows."

"The mighty whale shark is the largest species of fish in the world with specimens up to 60 feet long! Unlike many of their kin in the shark family, whale sharks are nonviolent, eating only plankton and such. They grow slowly and live long, relaxed lives of filter feeding and leisure in warm waters. So if you ever have to choose a fish as a roommate, you could do worse than the whale shark.                                            Unless you can't swim. "

Chip will say this when given a Whale Shark:


 * "Hmm. I wonder, do whale sharks taste much like regular sharks? Or are they a bit more blubbery? Obviously, even if I tried to eat this all in one bite—and I did try once—I couldn't do it! Just not happening!"
