Free Gifts

Early issues included a cover-mounted free gift^[6] the first issue included a "practical joke", for example a joke chocolate biscuit. Issue 2 featured a Squirt Ring. Issue 3 bore a Magic Numbers card game and Why Be Bored? book covers. The inner pages of the latter continued for several issue after.

Annuals

Annuals were printed from 1980 to 1986 - as was often the case with British titles, these hardback books outlasted the weekly comic by some time. They mixed original and reprinted material, with much of the new material being drawn by different artists than the weekly strips due to the lower page rate paid to artists.

Summer Specials

Summer Specials were printed from 1980 to 1982, again mixing reprint material with new strips (which again featured different artists).
