Barbie Lot of picnic table, dog stroller, oven

This is a lot of three Barbie accessories including the expandable puppy, dog stroller, picnic table and oven. The oven uses three AAA batteries, however, when I tested it with brand new batteries, I was not able to get it to work. There is some slight corrosion on one of the coils. It’s possible it could be cleaned and in working order again. Message with any questions!
