[hellywelly4]

You're a bit naughty, aren't you, that's all the words they give (in Compers News). Can't you do any by yourself?

[boxtops]

Does it have to be a word in itself which fits in?

No 3 could be blENDer as well as blOATer

A letter is highlighted in each word which all together make the word required at the end. The prize is a £10 Iceland voucher. The three letters required in each word, is a word in itself, if you see what I mean, so it can't just be a random group of letters - seaweed would fit because the three letters in the middle are AWE
