Sometime later after viewing the Litleonid meteor shower, Squishy went off to a nearby tree where it can sleep. Meanwhile traveling with the gang it met Professor Sycamore at a Pokémon Center who wanted to analyze Squishy. Īs they continued on, Team Rocket tried to capture it but with the help of Clemont's Bunnelby and the others, they got away but when the group was cornered, Squishy attempted to transform to protect its friends but when Ash and his friends came it stopped. However, little does it know, Squishy's 10% Forme was shown to Team Flare Scientist Xerosic and their Leader Lysandre as they continue their research on it. After the group said farewell to Sawyer, Squishy was in Bonnie's bag looking around in order to be sure that Team Flare wasn't pursuing them. Seeing how much Bonnie cared about it even though they just met, Squishy decided to travel with the group. Now with strength, Squishy then used Land's Wrath, which makes Bryony and her henchmen retreat. With no other option, Squishy used its ability to call the Zygarde Cells and then all fuse with it, turning into its 10% Forme. However, Squishy fell out of Bonnie's arm when she slipped, then was comforted by two Grunts and Bryony. Squishy left with Bonnie, Clemont and Serena while Ash and Sawyer battle Team Flare. Although, Squishy was saved when Bonnie and the gang arrived to help it. However, while everyone was asleep, Squishy sensed that Team Flare was close by then tried to leave the gang in order to make sure it won't be attacked but failed as they were able to catch up to it. After getting to safety, Squishy was amazed and surprised that Bonnie knew it was asking for help. Through Ash and Sawyer's teamwork, Squishy was saved and Bonnie grabbed it then were able to escaped. Squishy was ambushed by Team Flare as they were able to grab until Bonnie and her friends arrived at the seen. Unfortunately, Squishy got separated from Bonnie when group of Dodrio that were being chased by Sawyer and his Grovyle. After Bonnie decided to take care of it, it was nicknamed " Squishy" because of its squishy body. However, Squishy was discovered by Bonnie and Dedenne as it freaked out then tried to leave until she caught it. While running, Squishy discovered a bag that belonged to Bonnie and decided to rest inside of it. At the end, Squishy was shown to escape from Lysandre's lab and out in the opening where as the sun shines on its shadow in the 50% Forme Zygarde. Squishy called down to Chespie but it called up to tell it escape. Using Vine Whip, Chespie opened the air vent and put Squishy in there so it would safely escape. When one of the scientist was about to grab Squishy, Chespie used Vine Whip to protect it and carries it to the wall.
Increasing the output of the experiment, Squishy started to shrink, causing the whole case to explode. Squishy's call lead Chespie to find where it was and while a strange aura surrounded it as it continued to calling out to her. At Lysandre's lab, Squishy was seen to be in some sort of a glass case with some trees and plants while the researchers were experimenting on it.
Squishy tried to protect the Zygarde cells from Team Flare, but it was unsuccessful as the 50% Forme Zygarde was captured in order to be used in researches. When trying to have a conversation with Z-2 and later Bonnie via telepathy, Squishy speaks in a higher pitch. In Dream a Little Dream from Me! a Darkrai forces a nightmare upon Pikachu and Team Rocket's Meowth, as well as Squishy- the fire creature may be representative of Team Flare, as they are constantly hunting it and its other Core counterpart, Z-2.
Squishy, as a Core, uses Zygarde Cells to monitor the environment, and will typically do so before it sleeps. It was shown to be protective when its friends are in danger in Meeting at Terminus Cave! and it chose to remain with them in A Cellular Connection!. Squishy was originally a Pokémon wary of humans, as shown when Bonnie found it when it shook and tried to go deeper in the bag, but being with Bonnie changed its opinion about humans.
