The Marshalls and Cha-Ka are out one day together, their mission to locate the pylons to see if there is any rhyme or reason to where they are situated, while Cha-Ka carries the picnic basket lunch Holly has prepared. Cha-Ka goes missing for a time. When the Marshalls eventually locate him, he is excited about what happened to him. It seems like he is trying to say that he was being chased by Spot, when Spot mysteriously disappeared, the same fate which also befell their picnic lunch. The spot where this all occurred seems to be where a pylon should be located, but where one is not to be seen. Just then, a hole opens up in the ground, through which Cha-Ka falls. The hole then closes up behind him. Before the hole closed up, Will noticed that the hole seemed to be bottomless.

When referring to the Allosaurus that is shown eating a carcass, Rick calls it "he," implying that this Allosaurus is not Big Alice, the female guardian of the Lost City. This is the first time in the series that it is implied that there are more than one of a particular dinosaur species (except for Brontosauruses Emily and Dopey and the multiple pterodactyls that are often pictured flying above).

Similarly, rick refers to the Coelophysis as "a Spot," implying that there are multiple Coelophysises in the Land of the Lost, all of whom the Marshalls refer to as Spot. See more »


The Marshalls are able to track where Spot ostensibly fell into the hole by seeing where Spot's footprints end, yet the footprints pictured look nothing like a dinosaur's footprints, which would show its pointed toes, like a bird's footprints. Spot's footprints are more or less rectangular.

Also, when Spot runs, he drags his tail. Shouldn't his tail leave an imprint in the dirt just as his feet do? See more »
