The head including a top section (26) and a bottom section (28) having a mouth formed therebetween with a coiled tongue (30) therein. When a toy vehicle traveling along the track enters the head from the back, the vehicle will be allowed to exit through the mouth of the head if it has sufficient energy to completely unroll the tongue. However, if the vehicle does not have sufficient energy, the tongue will not completely unroll and will be retracted back into the mouth, to its normal rest position, pulling the toy vehicle with it.
