Douglas to Otis

"Bionic Dog" is the 5th episode in Season 4 of Lab Rats: Bionic Island. It first aired on April 8, 2015. This is the 77th episode overall. It features the first and only appearance of Otis


When Douglas' long lost dog, Otis, shows up on the island, Chase becomes severely allergic to him and Adam instantly bonds with him. Meanwhile, Leo gets a new smartphone, but becomes addicted to it's assistant, Shelly.


Adam Davenport brought a dog to the bionic island and Douglas reveals that its his long lost dog, Otis. However, Chase started sneezing because he has allergies so Douglas said it's time Otis have to leave but he lied and said to Adam to hide the dog. Meanwhile Leo gets a new smartphone and fell in love with it's assistant, named Shelly. Bree asked him to stop bonding with the assistant because he wasn't going outside or talking to real people. When Leo is gone it seems that Bree also fell in love but with another phone assistant named Liam. Bree accidentally uploaded Liam to Leo's phone. Leo came to take his phone and realized that Bree got rid of Shelly and installed Liam to his new smartphone. Leo got angry and started fighting with Bree to get his phone back. Suddenly there was a crash from the weapons storage room, Douglas was present but not injured. Adam, Chase and Otis went to help Douglas. Chase finds a tripwire that proved it was no accident. Adam asks Otis to sniff the wire to find who did it and he went to Chase to frame him. Otis' motives are revealed: his plan is to eliminate Douglas. Adam and Douglas are playing with Otis when Chase comes in and says he can't find out who did it, then leaves to check the security footage. He sneezes, and pleads with them to get the dog off the island. Douglas decides to take the dog away, but Adam wants to say goodbye. Otis activated the override app on Adam which made Otis able to control him. He makes Adam lick Douglas' face and bite his leg. Douglas and Chase tried to stop Adam from acting crazy because they didn't know that Adam was being controlled by Otis. Chase reveals that Otis was the one who tried to kill Douglas by showing him the security footage. Chase scans Otis's chip and sees many abilities. Douglas said it must be Victor Krane who gave extra abilities to Otis, and gave him a mission to find him and take him out. They figure out that Otis is controlling Adam and that's why he's acting like a dog. Otis continues trying to destroy Douglas by shooting lasers at him. Chase manages to get Otis to stop by covering himself in peanut butter. Otis chased Chase and later he got stuck in a net. Douglas extracted Otis bionic chip and Otis is back to a normal dog. Adam jumped on Chase who was covered in peanut butter and started licking him. Douglas said that Otis's chip was removed and no one is controlling him. Adam reveals that he loves peanut butter and he wasn't being controlled. Then, as Adam, Chase, and Douglas walk toward the Hydroloop with Otis to take him back to the mainland, Douglas says he found a good home for Otis, with the Krane family. Adam and Chase give him strange looks, but he reassures them that the family has no relation to Victor Krane. Then, Leo and Bree came out of a room still fighting and they accidentally dropped the phone. Otis pees (urinates) on the phone which completely ruins it. Leo and Bree stop fighting and neither of them want it anymore.
