From early-mid 1980’s(?), book + tape children’s read along picture book. Brother and sister(?) visit all the planets in the solar system along with a ‘captain’ astronaut guy. There’s a part about each planet. There is music and sound effects in the production. In one part the captain almost dies on a space walk and the kids save him. I’ve been looking for this for decades now.
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.
