Super Grover

Continuity mistake: When Chunk waits for the gate to open after doing the 'truffle shuffle', a red balloon starts to blow up, but next shot it's a pink balloon that pops. (00:07:40)

Visible crew/equipment: When the Goonies are first climbing the ladder on the pirate ship to find one eyed Willy's gold, the second shot has a crew member waving his arm on the far left of the screen. (This is only visible in the widescreen version). (01:21:00)
