Phineas and Ferb In Down Perry-Scop

A backyard lake beside Candace's sunbathing spot becomes a rescue mission after Phineas and Ferb launch a homemade sub in Phineas and Ferb in Down Perry-Scop. Deep below, Dr. Doofenshmirtz waits in his own submarine, pulling fish toward his money-making scheme. Perry joins the brothers underwater. The lake stays safe only if the drains on the bottom get sealed before the fish are sucked in.

How to play?

Steer the submarine around rocks and floating mines, guiding Perry toward cracks in the lakebed. Crabs guard the sponge plugs, so pull those sponges away before you fire Perry's suction funnel into place. A sealed drain stops fish from getting pulled inside. Move on to the next opening and block the rest of them across the lake.
