Well, I've been trying for weeks now to find new glitches to make getting a lower time possible in various ways, I didn't find any helpful glitches I can recreate consistently (except one for the 100% category of speed-running I ironically don't play) yet but I sure found some interesting things.

On the N64 version in the first bus when the boss flies up after hitting you either the first or second time you can double jump into her... Ehr, Bottom and then stand briefly on her feet to jump out of view on the top of the screen. You'll fall down and the fight continues as normal afterwards but I found it pretty, especially as I stumbled upon it not when actually trying to hunt for potential glitches but during a failed speed-run.

I also discovered that for some reason if you jump through a milkshake but don't pick it up (By double jumping before hitting the floor), it plays a small part of the milkshake music.

Though it's completely useless in speedrunning any%, but may be usefull when speedrunning 100%: You can immediately enter a stage again after exiting it by spamming the hit button, before the B piece animation has stopped potentially saving about 4 seconds per level if you make sure you already have the time trials loaded in via the nephew enter glitch doing that first, then going to the levels to collect the B piece and toys and then doing gladstones speed challenge right after for every level.

I can now also confirm it's definitely possible to skip one of the levels in area 3 as I remembered form childhood (got it working on N64, while in childhood I played the PC version so it might not actually be caused for the same reasons, even if I don't remember how to do it on the Dutch disney Classics version of the game either), I've been checking all combinations of levels reached possible in any order possible as much as possible (And some different tricks/deaths and routing oddities around the B pieces) till that point but I can't figure out why it happened and I wasn't able to do it a second time. I am not actually very experienced with glitch hunting (or speed-running for that matter), would anyone have a clue how I could figure out why a glitch like this would happen so I can start to figure out how to recreate the glitch reliably? I'm sure it'd be great for everyone if we can get another level skip to work.

I sadly didn't record any of the above findings, I didn't see much purpose in recording hours upon hours of trying random combinations of levels (and trying various tricks in various levels), but I feel pretty stupid in hindsight considering I got the third world skip I was talking about to work that one time.

I hope any of the information above helps and/or that someone could help answer the question I asked.

I can confirm the skip SuperSqank provided appears to work in both versions of the game I have as a physical copy, but I can't get it to work in the N64 Emulator US Version, though it's not extremely useful to me, given the fact I only really do any% on this game.

No, I am not confusing it, I know you can enter the chase levels before talking to your nephews by trying to enter on a specific spot behind his back on the PC version in at the least world 1 and 3. The skip I am talking about isn't that, but it's rather stupid that I can't remember how to trigger it.

Ui_jess I just looked at your PC Personal Record, you where ahead of WR timestamps if you didn't need to do that extra level in world 4. You can skip (at least) 1 level in PC as well in both the second and third world (At least in the Dutch Disney Classics Disk Version), I discovered by accident as a kid, but I couldn't remember how anymore after I came back to the game 2 years ago after not having played it since I was like 8. :/

If you could give me the 48.38 run I can look at them side by side with mine, as I am almost 2 minutes ahead of you, to see what differences I could find.

The original PC game is hard to get running properly on windows 10 PC, especially the European, Dutch, Dutch Disney Classics and UK Disney Classics Versions (I have the Dutch Disney Classics and the basic European Version) (I am not sure of any of these versions except for available languages have technical differences). - They are also really hard to find over here, as Quack Attack was notoriously unpopular in the Netherlands, for people who would want to play the game for speed runs.

The main reason I switched to emulator is because of timing. The PC version can't be played in windowed mode in any way meaning that for me, meaning keeping live splits wasn't possible. (But you have seemed to manage, so if you could tell me how that'd be apreciated)

I did attempt a few runs on PC, but it's so frustrating that I can't keep my time properly. I've been trying to figure out how the skips on PC worked as well in world 2 and 3 (That's why I don't have any new submitted runs since my last one), but so far I've had no luck.

MasterLeoBlue for me (Actual disc) it runs fine on Windows Compatability mode for Vista and Windows 7 Package 1, but you CANNOT change the graphic quality, it'll be stuck at lower. The game does not have windowed mode available, btw.

For Speedruns I tend to use N64 with Emulator. Inputs for PC are a bit inconsistant meaning it's hard to be consistant on the PC version in speedruns.
