Child's Play

The Grundal (also known as a Dromaeosaurid Theropod Grundalicus) is a reptilian predator that roamed Ninjago in prehistoric times. By the time of the cartoon series, its species was long extinct, with a skeleton on display in the Ninjago Museum of History.

The Grundal appeared in "Child's Play" and made a later appearance in "Ghost Story" (in Sensei Wu's story).


Ghost Story (Flashback)

Soon after discovering that he was not the Green Ninja, Morrothrew a stick into a Grundal's cave, angering the beast. It pursued him until Wu intervened and saved him.

Child's Play

Lord Garmadon attempted to resurrect the Grundal with the power of the Mega Weapon, seeking to use it as the ultimate anti-Ninja weapon. The Ninja interfered with the ritual, causing them to be reverted to children - unfortunately for them, the Grundal was still revived and began stalking the city in search of its prey.

With their fighting skills reduced with their age, the Ninja were helpless against the Grundal, but Lloyd took them to Rufus MacAllister's comic book store, where he felt that they could find some defense against the beast. Using light-up illuma-swords, the Ninja were able to keep the Grundal at bay for a time, but the prehistoric monster eventually knocked the weapons from their hands.

The Ninja were only saved by the arrival of Nya and Sensei Wu, who had brought age-increasing Tomorrow'sTea with them. Despite being in range of the tea's effect, Lloyd threw the tea at the Grundal, undoing the time-reversal spell that had revived it and de-aged the Ninja. The Grundal collapsed into a pile of bones once again, and the Ninja were restored to their former selves - along with Lloyd, who was now a young adult.

Winds of Change

A statue of the Grundal was part of the Ninja exhibit at the museum.

Abilities and Attributes

The Grundal is fast, powerful, and resilient, having a hide immune to ordinary weapons. However, it is a nocturnal creature, and thus very vulnerable to light - even the relatively meager light projected by toy illuma-swords is enough to make it flinch.

Its claws can tear through metal and its senses are keen enough to track even a Ninja. It constantly secretes large amounts of viscous green ooze from its mouth - presumably some type of poison - but its effects are unknown.

  • It resembles a large theropod dinosaur such as Giganotosaurus or Tyrannosaurus, rather than a dromaeosaurid.
  • A model of a Grundal was on display in the Ninja exhibit at the Museum of History.
  • As seen in "Ghost Story," Grundals were still alive when Wu was a young man, but went extinct sometime afterwards.
