Buffy and Willow have a nice classic sitcom montage where they keep cooking cookies until they get it right. No sooner do they finish when Giles comes with information. It would seem that the real teacher has gone missing. Something we already know. So what does Buffy do? She hits the streets for information. Slayer style.
She all but gives up as the morning sun starts to come up. That is when she hears a scream from inside a local bakery. She rushes inside to come face to face with the giant tiger and gets her ass handed to her. The baker runs off and the tiger grows bored, leaving Buffy alone.
Now here is how you know that McDonald is a skilled writer. There are a lot of hints at things to come later in the story. All sprinkled in, to the point that you wouldn't even notice it if you weren't paying attention. Buffy almost blowing up her house, the Fry the Tiger Café. All important hints to the ending of the story. That's a master right there.
The next day in class the teacher shits on Buffy's cookies but loves Xander's dessert. As luck would have it, Xander bought them from the same bakery that the tiger attacked that morning. The teacher asks Xander to stay after class while Buffy heads off to meet up with Willow and Giles. Giles figured out that the giant tiger likes to collect humans to cook for them, this tips Buffy off to who the tiger is, the new teacher!! She makes it back to class just in time to witness the tiger attacking Xander. She tries to stop him but the tiger is just too strong. He takes Xander and flees, leaving a defeated Buffy behind in his wake.
Buffy, Giles and Willow find the tigers hideout in the Fry the Tiger Café. Willow made two fake desserts full of the same ingredients that Buffy almost burnt her house down with. Buffy distracts the tiger while Xander mixes them in with the rest of the food. The tiger takes a bite and it's night night tiger. The day is saved once again thanks to the Scooby gang! Well that and a sword to the eye delivered by Buffy.
After everything is said and done Buffy finally turns in good well cooked cookies! To the real teacher this time and Willow even gets a good grade on her art. To be fair it's because the teacher thought it was abstract, it wasn't. But it is a fun end to a fun story and a nice addition to the slayers journey!
