As the Boov are using the anti gravity balls to remove items they deem useless we see one of the items being removed are toilets, but toilets are seen throughout the movie.
At the beginning of the movie, Captain Smeck says that he found a new planet in the Milky-Way Galaxy. About 14 Minutes in, Oh accidentally sends an invite to his party to the whole galaxy. If The Gorg wasn't in the Milky-Way, then he would've never gotten the invite. So nothing would've been wrong.
In the party invitation that Oh sends to everyone, he used party music and had clip art of himself dancing in the invitation, yet, when he's in the Slushious with Tip and she plays a song, he starts involuntarily dancing and claims "Boov do not dancing"
When Boov lie, they turn green. However, when Officer Kyle lies about "erasing" Oh, he does not change any colour. That is because he believes he HAS accidentally erased him.
When Tip and Oh destroy the Gorg drone, a chunk of it breaks off and hits Slushious on the side, causing Oh to lose control of the car and crash it. Afterwards, it shows all of the slushy fuel leaking out of the severely cracked slushy dispenser fuel tanks, installed on the back of the car. For this to happen, the car would have had to be hit on the back, not the side.
When Oh and Tip land in Australia, he turns Slushious off by pulling the key out of the PUSH START BUTTON.
Tip pronounced the French word "chat" as in the English word chat. Ch is like the English Sh and the t is silent.
Tip can drive cars although she's still very young.
After arriving in Paris, Tip and Oh snatch Vincent van Gogh's "Starry Night" out of the hands of an alien who was about to eat it. The painting has been at the Museum of Modern Art in New York City since 1941.
In the BBC One print, instead of the correct 20th Century Fox logo, the Paramount Pictures logo is shown, even though DreamWorks Animation leaves Paramount for 20th Century Fox as distributor in 2012.
As the Boov used anti-gravity magnetic balls that gathered in clusters things they didn't need (such as bicycles), a group of toilets in the air make a flushing sound but that's impossible because a toilet cannot flush without water.
After Kyle Catches up to Oh, and Tip and the gas station explodes, the scene in Paris shows Kyle arriving at Boov Command, but Oh and Tip, left the gas station before Kyle, and are Traveling to Paris as well, so how did Kyle get there before them?
Oh sent the e-vite to all Boov and that means all of the universe. The message is seen as an energy wave and takes 40 hours to reach the Gorg. Later in the movie, Oh stops the message instantly. This is not possible. The cancel e-vite should have taken 40 hours to reach the Gorg as well as it would also likely have also been sent as a wave like the first invite.
The evite Oh sent is meant to give directions to his domicile on Earth. If him and his fellow Boov are on Earth, there would be no need for Oh to give directions to Earth, since they are already on Earth. Instead, it should have given directions to his city, building, apartment, etc.
Oh would not play lottery tickets...Since he once claims that Boovs do not do anything if the odds are more than 50% against...he is seen serial scratching lottery tickets when con the way to París.
