Meet the Mudcrusts! Lowbrow Mudcrust is the lumbering, lazy head of the
family, who is happiest when he is squelching his toes in the slime.
That doesn't stop his wife Flora from nagging him and reminding him
that he's not the chief of the tribe. Their two children, Bogweed and
Fungus, are always fighting. Although Fungus doesn't have Bogweed's
brute strength, he is does have more brains.

The second book in the Mudcrusts series, Sabre-toothed Terrors follows the problems the Mudcrust family have settling into their new home.
