|“Behold, Dromaseric Theropod Grundalicus, otherwise known as the Grundal. Although now extinct, in its time it was the most fear and dangerous creature in all of Ninjago, with claws that could slice through steel, heightened senses that could detect its prey from miles away. It could track the stealthiest of Ninja, and once it had picked up your scent, there was no hiding from it.”|
|— Garmadon to the Serpentine in "Child's Play"|
Grundals (also known as Dromaeosaurid Theropod Grundalicus) were reptilian predators that once roamed Ninjago. By the time Lloyd was being trained to master his powers, its species was long extinct, with a skeleton on display in the Ninjago Museum of History. Using the Mega Weapon, Lord Garmadon revived the beast's skeleton and it attacked the Ninja, before eventually being destroyed by Lloyd, who turned older in the process.
Ghost Story (flashback)
Several years later, the Grundal species would eventually go extinct, under unknown circumstances.
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 Master Wu, who had brought age-increasing Tomorrow's Tea 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 teenager.
A comic about the Grundal is seen on the floor of Lloyd's room.
A statue of the Grundal was part of the Ninja exhibit at the Ninjago Museum of History.
Lloyd and Harumi are chased by a Grundal, this time in green. While the Grundal chases both of them, they fall into a crack in the ground. The Grundal then could not get to them and it walked away.
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.
- As seen in "Ghost Story," Grundals were still alive during the era of the Serpentine War (as Wu's flashback took place around the same time as Garmadon's flashbacks in "Spellbound"), but went extinct sometime afterwards.
- The appearance in "The Quiet One" could mean that some sort of Grundal species is still alive.
- Different sources spell the creature's name differently. A sticker in the 70657 Ninjago City Docks set for The LEGO Ninjago Movie (translated in Ninjargon), as well as the LEGO.com description for the Mega Weapon and the Dark Island Trilogy, Part 1 Episode Guide, spell it as "Grundle." However, Tommy Andreasen and captions for "Child's Play" spell it as "Grundal," which is more in line with the extended name of "Grundalicus."
