This wooden Skull Cave includes two pieces of track in the base to increase placement options within a track layout and create two tunnel entrances or exits. Lift the elasticated skulls on either end and guide your train through the skulls or journey through the fallen rock. Encourages imagination, dexterity and co-ordination. Most other major wooden railway brands are compatible with Bigjigs Rail. Made from high quality, responsibly sourced materials. Conforms to current European safety standards.
