When Manny and April first spot the sea lion, he has shoes and socks on. After taking off his shirt he dives into the water, and his feet are now bare without him having had time to remove his shoes and socks.
When April tells Hobie she plans to go to the caves with Manny, her hands are at her sides in one shot, clasped in her lap the next, then at her sides again.
The cable Max uses to tow out the buried truck disappears from his hands between shots, and he pantomimes attaching it to the back of his rig.
When Mitch and Cody discuss cleaning out the truck, a woman in an aqua floral print bikini walks behind Mitch twice going in the same direction.
When Lani tries to pull Manny away from the eel, she climbs down to the running board of the boat twice.
The episode deals with an electric eel that gets into the ocean near Zuma Beach, endangering lifeguards and civilians. Electric eels are fresh-water fish, and cannot survive in salt water (which will damage their gills and cause their electricity-generating organs to uncontrollably discharge).
The eel shown is not an electric eel but a moray eel.
