Make sure you continue to spam Macho and Tank Cat to the max. Bun Bun Teachers can't raelly advance if you span fast enough. If he moves forward to fast, you could always by Boogey Cat in the store as a 3rd spammer. Boogey Cat is a decent cat that can be used to spam in further levels too! If you are stingy, you can always use crazed macho and tank cat, if available. I used to be stuck on Cave Fillet too, but I was able to beat it with enough persistence.
