Home (developed as Happy Smekday!) is a 2015 computer animated sci-fi comedy buddy film that is DreamWorks' 31st feature film. It is based on the book The True Meaning of Smekday by Adam Rex. The film was released on March 27, 2015.
On the run from their enemy the Gorg, the Boov (Stephen Kearin, April Winchill, Brian Stepanek, and Lisa Stewart) find our planet, Earth, suitable for a place to call Home (get it?). Led by Captain Smek (Steve Martin), they commence their friendly invasion of the planet, relocating the humans to other parts of the planet while the Boov inhabit their homes. (Red Balloon/opening title sequence) One of the Boov, named Oh (Jim Parsons) is a more excited, free-thinking member of the species, who decides to invite all the other Boov to his apartment for a housewarming party. Not far from Oh is a teenage girl named Tip (Rihanna), who drives away through her home city after being separated from her mother Lucy (Jennifer Lopez) during the invasion, leaving her with her pet calico cat Pig and fueling her hatred for the Boov.
Oh runs into the street to find a Boov cop named Kyle (Matt Jones), who, like the rest of the Boov, are aggravated with Oh. He invites him to the party, and then decides to send a mass invite to every Boov on Earth. Oh hits "reply all", which actually sends the invite to absolutely every alien race in the entire galaxy, including the Gorg (Brian Stepanek). After being declared a fugitive, Oh runs into a convenience store to grab supplies, just as Tip and Pig are doing so. They come across each other, and after Tip's car fails to start, Oh transforms it into a fantastical, hovering craft that literally runs on slushies. Oh hitches a ride with Tip when he promises to help her find Lucy, but unfortunately, they must to go to the Boov Command Center in Paris and locate her from there.
After reaching the Boov Command Center, which is in the now-floating Eiffel Tower, Oh manages to get into his account, and deletes the message just seconds before it reaches the Gorg. He then plugs in Tip's brain to help her find Lucy. They eventually trace her location to Australia, where she is actively looking for her daughter. The other Boov then find the two and try to "erase" Oh, while Tip grabs the gravity manipulation system and flips it over, causing the whole Tower to tilt upside down, thus allowing ample time for her and Oh to escape and head for Australia.
When the two wake up, they see other Boov riding by them in fear, and realize that a Gorg ship is close behind them. Tip and Oh manage to knock it down, but in the process a chunk of it hits them and they lose their slushie fuel. They come across the fallen Gorg ship and find out that it is actually a drone. Oh recovers a special chip and uses it to get their car up and running.
Tip and Oh make it to Australia and see the Boov evacuating to their mothership. When they land the car, Tip starts to run for her mother, but Oh insists on evacuating with the other Boov instead. Tip gets angry at him for trying to break the promise again, and she declares that they were never friends. Heartbroken, Oh returns to the ship. The Gorg mothership come close to the Boov ship, but Oh pulls out the Gorg chip and uses it to fly the ship further away from the Gorg. The Boov become astonished at Oh's plan. Smek becomes upset and reminds everyone that he is the captain. Kyle grabs Smek's "shusher" (a scepter with a rock on top of it) and gives it to Oh, declaring him the new captain.
Tip rushes aimlessly around the city to find Lucy, but no one can help her. Oh returns to her side and helps her track down Lucy. The mother and daughter finally reunite and thank Oh. The Gorg mothership descends upon the planet, and Oh realizes that they want the rock on the shusher, since Smek had previously stolen it from them. Oh runs to the ship to try and get its attention, locking Tip and Lucy in the car for safety. Tip breaks out of the car and shines a light in the Gorg Commander's face to bring his attention to Oh as he holds the rock up. The Gorg Commander halts the ship as it crunches down on the ground, with Oh in its path. Tip rushes to rescue him, but Oh gets seemingly crushed beneath the machine. It backs up and Oh is revealed to be unharmed. The Gorg Commander emerges from his armor to show that he is actually a harmless starfish-like creature. Oh returns the rock to him, which turns out to contain millions of developing Gorg larvae; the next generation of Gorg, revealing that this Gorg is the last of his kind. He thanks Oh and eventually departs.
Two weeks later, the humans have returned to their original homes, and Oh finally gets to have his party at his apartment, with humans and Boov in attendance. Tip plays her music and gets the rest of the Boov to experience dancing for the first time, while other Boov, including Smek, party on the moon, and thousands of ships from other planets, including the Gorg, head to Earth for Oh's party upon receiving his invite.
