This is what directly caused everything going on to go underway. It sets the precedent for what King Mickey, Drewcification, and other such perpetrators will eventually do with toontown.co.uk.
DISCLAIMER: I do not have screenshots of what happened. I didn't think to take screenshots, as I didn't think the situation would blow up into what it became. The situation listed is based on what I saw in the staff chats and a recollection via reading Mickey's TwitLonger post on this event. It is worth noting, however, that a surviving piece of the premise still survives in the Google Drive leak (ClashStingOperation.zip) that was posted on toontown.co.uk, labeled as "unknown.png" in the root of the ZIP archive. You should still be able to download it from this link.
Drewcification and King Mickey frequently diss on Corporate Clash, both in Toontown Offline staff chats and in Toontown Offline public chats. Poppy pops into the chat and makes an issue on this, stating that they don't bad-mouth Offline like they do Clash. Mickey, as highlighted in his TwitLonger, is enraged by this and disagrees. Poppy leaves the Discord.
Loonatic comes back from her month long break and finds this mess. In response, she makes the sudden rule that "excessive bad-mouthing of other Toontown private servers and projects is not allowed" and that criticism must be "civil and non-hostile." Mickey makes issue with this rule and takes to the staff chat to be passive-aggressive towards Loonatic for having Clash's backs about this. Progressively, Mickey becomes much more rude and aggressive towards Loonatic and she brings up being able to act professional in a team environment. Mickey, who is very for the idea of Offline never being a serious project and being a friend group first, and pretty much derailed the conversation to the point of Loonatic firing and banning him out of essentially panic.
Soon after this ordeal, King Mickey posts his TwitLonger post about what he faced publicly on Twitter.
I personally believe that Mickey lost all credibility as soon as he started to swear and verbally attack Loonatic. I believe that aggression solves nothing, in that it perpetuates even more aggressive actions. This is precisely why he got fired and banned from Toontown Offline.
I also find it particularly troubling that he is so attached to the idea of the "friend group"-style approach to teamwork that Offline has gone under that he labels more professional approaches to teamwork and public relations (such as Corporate Clash's) as "corporate." Why I feel troubled by it is because the Toontown creative community as a whole has been maturing as time went on. I still believe that Toontown Rewritten takes itself too seriously, but Corporate Clash as of right now is the best mix of professionalism and casual interaction in the Toontown community. They're on a level similar to TS!Underswap and other respectable indie games, I feel. Out of every Toontown fangame, Corporate Clash emanates this feeling of passion for their game and the community that I don't see anywhere else in this community.
The Toontown Offline team has always been a team that never grew out of the relaxed, laid-back approach to teamwork and public relations that game developers tend to follow when they first start on a project or are starting to get their footing. Usually, as the team became more experienced and as the game developed, so too would their behaviors among the staff and towards the community. Toontown Offline never really grew out of this, even after the team restructure that happened after the Offline Split of 2019. In fact, the team fully embraced this by essentially calling themselves a friend group. Everyone on the team was highly trusted. There never was a structure made to handle bad actors, which has so far led to these huge blowups that affected a large portion of the Toontown community. It happened back in 2019, and it's happening right now.
Mickey's disgust for a more professional team environment is likely entirely based on how he truly viewed the Toontown Offline team. From what I can tell, he viewed the team first and foremost as a friend group. Everyone in the group are all friends, and anyone that says otherwise is out for blood. The last part could be a result of how the events of February 20th have been affecting him, which he mentioned in his TwitLonger post. Regardless, he was firmly against the idea that Toontown Offline should under no circumstances resemble a corporation. After all, that's what Toontown Rewritten is doing, right?
Regarding Loonatic, I feel that she shouldn't have acted so rash in her situation. However, I can see why she did what she did. She likely became very flustered by Mickey's relentless aggression, likely seeing that it wasn't possible to reason with him. It wasn't an attempt to butcher Toontown Offline for the glory of Clash, like what the toontown.co.uk operation are trying to paint. I can TELL you for sure that it isn't the case because Corporate Clash didn't have a reason to go after Toontown Offline. They were a successful fangame, and the Toontown Offline team wasn't actively trying to cause harm. The events of 5/24/2021 are likely where Corporate Clash figured that there was no hope in cooperating with Toontown Offline and made their staff rule that you can only be contributor of Corporate Clash and no other project. It's sad, but it was necessary regarding what was happening.
Overall, this was a situation that could've been avoided if Mickey acted rationally and open-mindedly. Instead, he decided it was more worth it to flip the table and cause a huge fire because he didn't want Toontown Offline to go "corporate" in an environment where the Toontown creative community was going more "corporate."
