This little frog is now in a big pond — thanks to a confessed thief who liberated the amphibian from the fishbowl it had lived in for more than 22 years.

Frog owner Thomas Liotti, a lawyer from East Garden City, L.I., said the South African tree frog was worth $900 and had been given to him as a present two decades ago.

For some reason, would-be client Fernando Castro got annoyed at Liotta and on his way out stole the fishbowl with the office mascot in it, according to court papers.

He took it to another lawyer’s office, and left it with a staff member, suggesting it could replace that attorney’s pet fish, which recently died.

The staffer then released the frog in a creek, Newsday reported.

Castro was arraigned Friday on a petit larceny charge and held on $500 bail.
