There are a few silly things to do with Functioner. Here are a few of them:
Sometimes, there may be dead pixels on the screen, among image popups (the latter can be seen in Functioner 1 onwards, NOT DOS System).
The FunkOS sometimes advertises Functioner since it has more systems.
The FunkOS 8 logo has googly eyes.
Functioner sometimes complains about the things it doesn't know to do.
Ever since the release of the wiki, you can find a classic mode commonly in systems after Functioner 96. Since the FunkOS IⵔIII update, that chance is raised to high in modern systems, but if you're lucky, you will find a very updated Screensaver game mode, where the item doesn't move and appears in random positions before fading out and hiding into a different position, making it hard to play the game mode.
Something similar to the last one, which was introduced during the FunkOS Iⵔ update. Since FunkOS Iⵔ and FunkOS IⵔII have been released, users are finding it hard to see new things. If you boot into Functioner, then you will see that Functosh is locked. Try again, it doesn't unlock, until it unlocks itself. If you press it, you will get into an old system (most specifically Functosh System 5) and instantly boot into the B OS Show or Progressbar Largehorn (Show).
However, if you are lucky enough, you may get a "searchlight" screensaver game mode in FunkOS Iⵔ+. The Functosh is now moving around and does not go in random positions. It also leaves a trail. You can find more on FunkOS Iⵔ and its aesthetics on the main page.
Even though Functioner REMOTE 3.6 in-game counts itself as a server system, in the Progressbar95 universe it is counted as a consumer system.
Looking into the FunkOS IZ Functosh icon more closely will give you the name of the CPU, in case "N1". Inside the red Functosh sprite's costumes, if you look closer it says "O1", which stands for Opponent 1.
In FunkOS IЗ (new), the CPU names are "N2" and "O2", respectively.
In FunkOS IЗ (new), the colours of the Functoshes in the Multiplayer game mode are hilariously referred to as Azure and Tomato, respectively.
