This is a children's version of Malefiz aka Barricade. You only have 2 pawns instead of five. There are only 4 barricades instead of 11. And the board has fewer fields. If your pawn is taken by another and this happens on the top half of the board, you don't have to start all over again. In that case you may start again in the middle of the board. There are also secure places on the board. If you are on a blue field with a drawing of Pluto, you're safe from attacks of other players. Barricades can not be placed on the blue fields. There are even simpler rules (with one pawn) for children between four and six.
Though it is somewhat confusing, Ravensburger produced a Spongbob version of both Junior Malefiz and Barricade, the latter is a version of Malefiz. These two different items used the same cover artwork but differed on the board layout, rules, and numbers of figures.
