In "Old Chief Wood'nhead", Ray and Martha Spruce watch as Ben Whitemoon drives off in his limo and there is still bright daylight overhead. In the next shot of them re-entering the general store, you can see through the door that it is suddenly night outside.
Not sure how this slipped past the filmmakers but Derek got sucked through the wooden boards of the raft, planks snapping. At the end, Poncho swims away with the raft behind fully intact.
When Old Chief Woodenhead grabs Sam's hair, he doesn't have all of it in his hand, yet in the next shot he does.
A display rack which Sam knocks to the floor in "Old Chief Woodn'head" keeps changing position on the floor.
In "The Raft" the angle of the car, and it's distance from the water changes.
The final frames of "The Raft" segment, show the car on the shore, and the radio is still playing. However, after sitting idle for an entire day and an entire night, without the aid of the alternator to charge it, the car battery would have died long before the allotted amount of time had passed.
In just about every scene where Old Chief Woodenhead (the wood-carving) is seen standing in front of the store, you can see slight movements by the actor who played him. However this is NOT a mistake as the characters in the film even give subtle acknowledgment the wooden statue has moved. This is to show that the statue was actually "alive" all along.
After Deke reaches the raft in the middle of the lake, he lights a joint. However, due to the fact that he has just been swimming, this joint should be wet and therefore unable to be lighted.
Sharp eyes will note that Deke had placed his joints (and a small size Bic lighter) in an airtight pharmacy prescription bottle stuffed in his waistband, which would keep the contents dry even when submerged.

In "The Raft" segment, when Deke gets pulled down by the monster, his body is forced through a sizable break in the raft planks. His hand could not have gone through the narrow gap between intact raft planks, as shown when he is finally pulled under and his class ring slips off. Nor could he have reached up through the gap from underneath since his ring would have blocked him.
When "Old Chief Woodn'head" applies the war paint to his face, his fingers bend revealing that they are actually foam rubber.
When "Old Chief Woodn'head" comes to life, his bow string can be seen pushing into his arm revealing that the "wood" is made of foam rubber.
When Fatso is eating chicken from his seat in his caravan, Old Chief Woodn'head shoots 3 arrows, (one into his chest, one into his left hand, and one into his head). In the head shot, the cap he is wearing is raised, making it clearly visible that the arrow head shot did not go through his head, but above it, therefore exposing the bloody makeup effect.
When Deke gets dragged through the hole in the raft with his leg sticking upwards, the prop leg is obvious as someone bending in half at the waist would have their foot above their head.
When Deke gets out of the water to climb onto the raft in segment "The Raft" the bag of marijuana he tied to his bathing suit is missing and nowhere to be seen until a few minutes later it is in his hand.
When Sam and his pals speed away from the store, you can hear tires squealing even though they're driving on dirt.
When Annie Lansing is looking out of the back of her car to see if the hitchhiker is still running behind her, he has disappeared but instead you can see a crewmember through the upper left corner of the car window.
When the 'oil slick monster' just misses Laverne, you can see a crew member under the raft (probably operating the mechanical special effect)
Sam only calls Fatso by the correct name once; after that, he refers to him as Fat-stuff.
