The dolphin briefly got stranded on Tuesday while trying to swim back to sea, with experts keeping a close eye on it to make sure it was safe.
Some people were worried for the dolphin's health

The coastguard were also deployed - to make sure spectators trying to spot the dolphin were safe.
But good news! After two days of the dolphin swimming around lost, it looks like the story has a happy ending.

Goodbye, lost Welsh dolphin who was apparently called "Dave" (according to the Chester Chronicle). We hope you enjoyed your visit to Chester.
