*Pebble woke up one morning, along with Sprout. Sprout yawned and stretched.* Sprout: Morning Pebble! *Pebble barks and sniffs Sprout's arm* Sprout: Huh? Oh, I forgot to take a shower last night. Let that be our little secret, okay? *Pebble opens his mouth, his fangs showing* Sprout: Pebble? *Pebble suddenly bit down on Sprout's arm, he froze and screamed. You, Tisha, and Cosmo were in the library, looking for some books for Brightney. You three suddenly heard Sprout scream* Cosmo & Tisha: SPROUT!? *You three ran to Sprout's room to see Pebble biting on his arm and not letting go, Sprout was crying in pain.* Tisha: Pebble! Let go of him! *She grabs Pebble and tries to pull him off. Sprout cries out* Sprout: Stop! Please! *Cosmo runs off to get a medkit. Dandy suddenly shows up, hearing Sprout screaming. He runs over and sees Pebble biting Sprout* Dandy: Pebble! Stop!
