324S: Haunted House Mystery; Culprit Is A Pet Frog

This was a book on cassette – it may have had an accompanying read along book.  I checked it out from the library all the time in the mid to late 90’s.

There was a group of kid detectives who were asked in to investigate strange noises in an old house and prove it wasn’t haunted. There was a sick, bedridden boy visiting the owner of the house. After investigating, the detectives found that the sick boy had a secret pet frog that was causing the spooky sounds. The sick boy might have been visiting from a different country.

317D: Little Girl Makes Lost Bear Oatmeal

I’m trying to find a children’s book that I listened to on tape when I was little. I think this would have been early 90s so the book would have been published between the 80s and 90s.
It’s about a bear who gets lost and a little girl takes care of him. I specifically remember her feeding him warm oatmeal filled with things like nuts, fruit and honey. I think Santa makes an appearance at the end? I’ve found lots of books with various iterations of Little Snow Bear in their titles but none are what I’m looking for. A woman narrates the book on tape. Don’t know her name.
