What is Biff, Kipper and Chip's surname?

[Pacific]

I need to know because I am teaching the Brownies to write and address a letter properly.
Thank you!

make one up!

I don't think they've got one have they? Aren't they the annoying magic key kids?

I'd make one up - Biff, Kipper and Chip Dull comes to mind

Doesn't look like they have at this from the website "Mum calls Dad the 'fourth child of the family" - fgs! It's here

Absolutely agree re dull MM!

Ds has only just started on these and I didn't know there were two extra children. Give them different surnames because it certainly looks like the "fourth child" Dad is not the genetic Dad of all of the children! Must say, when looking for a boyfriend, I don't tend to find the "extra child" men the most appealing ones! However, all credit to him as he has fallen for a woman with 4 children all aged 7!

DWC, I'm certain your children will excel at school

Biff, Kipper and Chip are from the same family. Then they meet an Indian brother and sister and a black brother and sister and they all have adventures together, iirc.

Oops! Didn't mean to start an argument. Shall I just settle for 'Smith' then?

Dd always tells me off for saying 'he' when talking about Biff.

I think the books are really really boring and so does dd. She has to read one a week and answer about 10 questions on it in a book. It's a right pain, as she doesn't enjoy doing it and neither do i.

Might be too late ! Is n't it Robinson ? iirc from the Magic Key cartoons
