March of the Armoured Beasts

Jamie and Tom return to the dinosaur world and discover a baby Ankylosaurus stuck in thick mud, unable to free itself. The boys must act quickly to rescue the young dinosaur before it's pulled under, but their plan is complicated when the massive mother Ankylosaurus arrives, swinging her powerful clubbed tail. As the tension builds, the two friends use ingenuity and courage to save the baby while trying to avoid the protective parent's wrath.
