Product Description

Grumblies live in secret, hiding from the eyes of mankind. Short- tempered and full of mischief, bands of Grumblies roam the wild places of this earth, creating mysterious earthquakes, paranormal tsunamis and supernatural volcanos.

Could you tame such a creature?

Poke, shake, tilt and roll them, but beware: the more you mess with Grumblies, the angrier they become. When they reach their breaking point, you could trigger a massive meltdown of rumbling rage! Each Grumblie cycles through different levels of anger as you play—and once their meltdown is in full swing, only you can calm them down. With over 40 fuming reactions and custom sounds, each Grumblie has its own personality and design.

Hydro is a monster of tides and waves, created from sparkling surf and black ocean depths. In the wild, he wades through tsunamis and floods. Once captured, he grumbles and roars until you unleash his fury. Inspired by the power of rushing water and the pull of tides, Hydro is one seething Grumblie.

With hidden features, angry sounds and secret reactions for kids to discover as they play, Grumblies are interactive toys with a difference: they’re furious!

EU Warning:   Not suitable for children under the age of 3 years due to small parts which could cause a choking hazard.
