is a re-release with illustrations redone by Carol Thompson.
Janet loves how her mother calls stuff "thingamajigs" when she can't remember the word for them. Janet wants thingamajigs of her own, so she starts collecting small items she sees every day.
Jimmy wants to play with Janet's thingamajigs, so Janet wraps them up in brown paper bags and keeps them on her bed to prevent him from messing with them. The bags rustle every time Janet moves on her bed, and her mother says she sounds like a mouse in a wastepaper basket.
This short story was funny to me because my kid also likes to collect anything and everything. I think it's a perfect example of how kids like what they like, and if you give them the space to get it out of their system, they'll come through it on their own and save a lot of disagreements!
