Goof: We see the other Superfriends gather around Superman (Batman included) then the next second you see Batman ride up on his horse.
Batman expressed some concern that the explosive impact from the laser lances in his joust with Superman might finish him, yet he comes out pretty well unscathed even though Superman is much stronger and the explosion actually did restore his memory. I know Batman's a great superhero, but he is human and should have been more seriously injured. And what about their horses? If anything, their being closest to the explosion should have resulted in their certain deaths.
After Superman's memory is restored, he's on the ground in his Black Knight armor, asking Batman questions. We then see Batman respond. Then we're back to Superman again, who hasn't moved a muscle, but his armor is gone and he's back in is Supersuit.
