The Glimwood Tangle appeared in JN055. Chloe went there alongside Ash and Goh in search of a GalarianPonyta and Rapidash. Whilst there, Goh spotted a Morelull and chased after it, causing him and Ash to become separated from Chloe. Goh eventually caught Morelull, and whilst trying to find Chloe, they wandered into Ballonlea and met Opal.
Chloe, meanwhile, encountered a Galarian Ponyta, who led her to an injured Galarian Rapidash. Chloe went off in search of a flower whose dew could heal Rapidash, only to run into a trio of Impidimp that stole her backback. After a playful fight with Bluk Berries, Chloe retrieved her backback and got the flower dew she had searched for, using it to heal Rapidash. As thanks for healing it, Rapidash let Chloe ride itself and took her to Ballonlea.
The Glimwood Tangle appeared in the Sword & Shield arc. After it turned out that Allister had sneaked into Professor Magnolia's van due to his interest in her Antique FormSinistea and Polteageist, the Pokémon Professor revealed that she had met them when her car had lost a tire while driving through the forest shortly before. Due to Professor Magnolia having forgotten to reset the route record on the van's auto driver, it ended up driving the exact same route as before and crashing again.
As the van stopped, Allister left it to explore the forest in the hopes of catching himself an Antique Form Sinistea and Polteageist as well, with Shirudomiria chasing after him. While doing so, she heard a familiar sound in the distance, which she recognized as the sound of her lost Toxtricity, Tera, who was engaged in a battle against a wildDrakloak. Due to being solely focused on the battle, Tera didn't pay any attention to Shirudomiria until it had defeated Drakloak, after which it happily rejoined its Trainer, while Allister caught the Drakloak for himself.
Glimwood Tangle was introduced as a Stadium card in the Pokémon Trading Card Game during the English Sword & Shield Series (the Japanese Sword & Shield Era). It was first released in the Japanese Explosive Walker subset and the English Darkness Ablaze expansion, with artwork by aky CG Works. It allows the players to ignore any coin flip results and flip again.
