Thrash, now no longer voiced by David, wants to drink Sierra Mist, now rebranded to Starry, but Crunch specifically said no because it is Crunch's drink and doing so will make him sick. Crash and Coco aren't allowed to drink it and so do Tawna and Lily, who are running an errand, which is why they aren't in this video, and me and my friends.
Despite being told no, Thrash pours Sierra Mist on Crash's bed and gets busted by Crunch and Coco and gets sent to New Zealand as his punishment and he must stay there. If Thrash escapes from New Zealand, there will be severe consequences.
The Sierra Mist brand may be discontinued, but it still exists on this video and future videos to pay homage to the defunct video game company that has Sierra in the name and publishes the Crash Bandicoot games in the era with their parent company, Vivendi Games, now merged with Activision to establish Activision Blizzard and cause Sierra to be subsequently dissolved, and my teachers in my elementary school that were drinking it.
Originally, I planned a two part Thrash Gets Grounded video where he sets foot into the rumble and gets punishments, but due to a change of plans, I have decided to change to a different route to not get to the point prematurely until the time comes.
