Rare TMNT stories

[Original TMNT Cartoon Fan]

I have some rare TMNT stories in different kinds of book form: Does anybody else know them. The translations are not direct.

*Den magiska kristallen (The Magic Crystal), an adaption of the Kirby story in the 1984 Mirage comics and the 2003 cartoon. Donatello wears purple, April wears her yellow jumpsuit. It's credited 1990. free after a story by Kevin Eastman and Peter Laird.
*Turtles i skolan (School Daze), credited Astrid Holm 1992. It is about the TMNT going to a school for one day and fight some cheating teens who sell and buy answers of homeworks.
*Ray Fillet slår tillbaka (Ray Fillet's Revenge), text credited Greg Steddy and Mirage Studios, 1990 but I googled and found out it was originally named "Ray Fillet's Revenge". It the story, Krang, Shredder, Bebop and Rocksteady have an underwater base and prepare to launch a missile. The TMNT hear about underwater earthquakes and get help from Ray Fillet. The TMNT and Ray Fillet don't know each other.
*Wingnut och Screwloose (Wingnut and Screwloose), text credited Greg Steddy and Mirage Studios, 1990. I googled to find it's probably the same that was named "Wingnut and Screwloose". The story is set in summertime, and is some kind adaption of the Archie comics version http://www.ninjaturtles.com/comics/archie/archie.htm (which I don't have), but also involves as subplot with Krang and Shredder using an airship, hidden in a cloud-like disguise, and using a weather making machine to cause New York City's worst summer in years. Actually, it looks like Wingnut and Screwloose die after attacking the airship by going right towards it, and so also Shredder and Krang (Donatello and Leonardo say they blew up both Shredder and themselves), but Michelanglo argues they at least save the summer.
*Tivolidramat (Undercover Heroes), credited Mirage Studios, 1991. It followed a cassette tape with the story. After googling, I see Stella Paskins is the name behind the story. The story begins with an old lady fighting off robbers, and April reports for Channel 6 that several criminals recently have left New York City, and Big Louie complain that criminals no longer are safe in New York City. Nothing is like before, so the TMNT decide to go to an amusement park led by Happy Jack and have fun. When arriving, people act violent and the TMNT soon learn that Happy Jack works with Shredder. They use a machine to manipulate the minds of people, turning them angry (Happy Jack is also manipulated, but the turtles aren't). But Michelangelo makes a joke, and everybody laugh. Happy Jack falls over Shredder's machine, which breaks and New York City is saved for this time.
