Ashes, Ashes - S1-E6

Polly Wants a Treasure - S1-E8
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
Continuity mistake: Kai orders his squadron to bring up their stingers on their bug ships, and in a side angle shows them curling up like a scorpion stinger. It then cuts to a close up of one stinger opening and it suddenly changes shape a little. In the side angle it looking more like a shark head with a visible hump on the bottom side, to being almost a perfect round football like shape in the close up. Also the space gas around the ship changes from green to white between shots. (00:02:35)
Yomigaere! Eiyuu Densetsu - S1-E1

Something Ricked This Way Comes - S1-E9
Continuity mistake: When Rick, Jerry and Beth are eating pancakes, Jerry has his fork in his, but when Morty walks into the room and Jerry mentions science fairs are a father/son thing, Jerry's fork is suddenly on the table beside the knife. A further two shots after, the fork is suddenly back in the pancakes.
