- There you are, Tigger. Castle Ridge. Practice your bouncing on that.
- Ha ha ha ha! I can get up there in only two bounces.
- Hmm. The best bouncer in the world can do it in one.
- Well, dust off that trophy, palaroo.
- Hmm. This is going to take some serious practicizing.
- Mm. Mm. Uh, nope. Nope, nope, nope. Don't like it. Don't like it at all.
- That stack of cabbages is nothing, but an accident waiting to happen.
- Oh, accidents only happen when Tigger is around, and I've got him gone for days.
- Aah!
- That ridge is impossible. I can't even make it with my bestest bounce.
