The earthworm's crop and gizzard feel different because they perform two different functions. The gizzard is hard to the touch because it is used to grind the soil the earthworm takes into its body. The crop is soft and more saclike because it stores food that the earthworm separates from the other things it takes in.
Touching an earthworm with a toothpick would likely not harm the earthworm as toothpicks are not sharp enough to cause physical injury to the earthworm's body. However, the earthworm may perceive the touch as a form of stimulation or disturbance and may react by retracting back into the soil for protection.
