The Little Pink Book / Field Trip

T1, E2: The Little Pink Book: When Helga loses her pink book, full of love poems about Arnold on the bus, it ends up in Arnold's hands. Now Helga must get it back before Arnold figures out who wrote the poems. Field Trip: The kids are really looking forward to their field trip to the aquarium - especially when they remember the scary Lock Jaw from their last trip. But, when they get there, they see that Lock Jaw isn't really that scary. Arnold notices how neglected the old turtle looks, and returns later with Grandma to set it free.
