Biff and chip magic key stories

[Tomorrowillbeachicken]

Sorry to be annoying but can anyone help me by giving me a list of the biff and chip magic key adventure books and in what order to read them?
I know some them start in blue book band but not sure where.

The key is found in the final stage 4 book called "The Storm". The first stage 5 book is called "The Magic Key". After that, some of the books are magic key stories, some aren't. I can't see a reason to read them in a specific order other than following the levels (i.e. It makes sense to read Stage 5 followed by Stage 6 etc and aligned with reading ability - but be aware they are not a phonic series).

Yeah, they are mostly keywords. My DS is reading stage 4 atm so will start with the storm

A site called reading chest and the Oxford reading tree site itself have lists
