Bugs Bunny: Lost in Time is a 3D platforming game starring, you guessed it, Bugs Bunny. In the game Bugs accidentally activates a time machine and ends up lost in time, and he needs to gather Clock Symbols to return to the present, going through various ages in the process. The game's setup is similar to Super Mario 64: Bugs needs to gather 120 Clocks to finish the game, and goes through various hubs with various levels to do that. There's also magical spells obtained at certain levels to open up secrets and get more clocks, like SM64's caps.
There are also Golden Carrots, another collectable item which is needed to open up certain levels (for more clocks).
There are two endings for the game (although the only difference is the background during the credits): One for getting 120 clocks and going to Present, and another for getting all 124 clocks and all 333 Golden Carrots.
The game is surprisingly linear for its setup. You often need to get all clocks of previous stages just to unlock the next stage.
I've compiled a list of how many clocks there are in each stage (used to form a route):
Clocks G. Carrots Requires (clocks unless stated otherwise)
Nowhere 1 10 0
Stone Age 1 1
Wabbit on the run 9 22 1
Guess who needs a kick start 1 5 5
Wabbit or duck season 1 0 50 GCs
Magic hare blower 14 31 80

Mine or Mine? 10 41 100

The carrot factory 8 15 90
The Medieval Times 1 30
What's cookin', doc? 15 37 30
Witch Way To Albuquerque? 1 8 65
The carrot-henge mystery 8 20 73
Downhill Duck 1 0 250 GCs
The X-Dimension 1 40
The Planet X file 14 26 40
Vort X Room 4 0 60
The conquest of Planet X 1 14 70
Train Your Brain 5 21 117
Total 124 333
*"Follow The Red Pirate Road" requires the Super Jump spell obtained in "What's Cookin', Doc?".
**The Yellow Carrots available at each hub require 99 Carrots to obtain. Therefore, for 100% completion 99*5=495 regular carrots also need to be collected.
From that I have developed this 100% route:
Stage (Clocks, Golden Carrots)
Start (0, 0)
Nowhere (1, 10)
Wabbit on the run (10,32)
Guess Who Needs a... (11,37)
Hey, what's up, doc (20,54)

F. Red Pirate Road (1) (40,107)
When Sam met Bunny (41,109)

What's Cookin' Doc (3) (85,206)
Magic Hare Blower (99,237)
The Carrot Factory (107,252)
Mine or Mine? (117,293)
Downhill Duck (118,293)
Conquest of Planet X (119,307)
Train Your Brain (124,328)
Hub Golden Carrots* (124,333)
*hub Golden Carrots will be collected in between stages, not necessarily at the end (that's time-inefficient, not to mention impossible because 99 carrots is the max you can hold at any 1 time)
**The revisits (marked with (1), (2) etc.) are necessary due to these stages requiring spells to get all clocks. These spells can only be obtained after visiting these stages at least once.
***Empty spaces inbetween level names indicate switching times. Yes, that happens surprisingly often.
Unfortunately, in PCSX the game freezes at the cutscene after finishing the tutorial part of Nowhere, so the game can't be TASed yet. The sound emulation's also poor, but that is a comparatively minor issue.
EDIT: Edited route.
