what famous soda brand was sued for allegations that their drink could dissolve an entire mouse?

The famous soda brand was Mountain Dew , which is owned by PepsiCo.

Quick answer

• In 2009, an Illinois man sued PepsiCo, claiming he found a dead mouse in a can of Mountain Dew.

• In court filings, PepsiCo’s defense argued that if a mouse had been in the can since bottling, the Mountain Dew would have dissolved the carcass into a “jelly-like substance” before the consumer ever opened it.

• This unusual defense is what made the case so widely discussed online and in forums, leading to the recurring question about “which soda was sued over a mouse dissolving in the drink.”

Mini background

• The lawsuit centered on product liability and whether the mouse could realistically have been in the can from the time of bottling.

• Media outlets and science sites later examined whether the acidity of Mountain Dew could actually break down a mouse carcass over many months, which kept the story alive as a viral, slightly gross trivia topic.

Forum / trending context

• The story regularly resurfaces on Reddit and similar forums as a “today I learned” or “weird lawsuit” post, usually summarized as “a man sued Pepsi over a mouse in his Mountain Dew, and Pepsi argued the soda would have dissolved it.”

• It is often used in discussions about soda acidity, urban legends about soft drinks, and as a darkly humorous example of a PR nightmare for a major brand.
