The lava crawler was a rare Voya Nui Rahi repurposed by the Piraka into a war machine. Its hard shell was partially cut away to make room for a battle platform with a multi-zamor sphere launcher. The massive, ill-tempered creature was difficult for even the Piraka to control, as it was easily distracted by the lava streams of Mount Valmai. This repurposed lava crawler was called the caravan crawler.
The caravan crawler was a Rahi of Voya Nui with a hard shell.
- The caravan crawler model was in the scale of the playsets, not the constraction figures.
