Spy Fox/YMMV

Awesome Music: Dry Cereal has the Car Chase, which is a really awesome song but gets mostly drowned about because of all the noise the car makes.
Hilarious in Hindsight: The Birthday Cake Bombs from Cheese Chase. Nearly a decade before Portal, the cake was STILL a lie.
That One Level: Cheese Chase's Level 75, Carnival of Clouds. It's riddled with narrow pathways that are all one hit kills as well as plenty of cheese that leads to death traps.
That One Sidequest: During the White Water path in Dry Cereal, one of the things mandatory is to beat Big Pig at Go Fish. He's very good at playing, so expect frustration to ensue.
They Changed It, Now It Sucks: When Infogrames re-released the first game, the British dub somehow made it over to the States. For some, the new voice acting ruins it.
