Free Halloween Coloring Page Featuring Grimmstone from Slugterra

This Halloween I am creating 5 different coloring pages featuring Ghouled Slugs from slugterra. Today’s Slug is 1 of 5 featuring the Grimmstone!

The Grimmstone is the ghouled version of the Rammstone slug. They have a pinkish belly, Blue stripes and a dark maroon back. Grimmstone has sharp teeth and red eyes making them appear unnatural and evil. Grimmstone slugs are made by engulfing Rammstone slugs in Karum-Zanul or Dark Water. The dark water also makes the Grimmstone far more powerful and increases it’s strength.

At 100 miles per hour, the Grimmstone turns black with a red belly and green fists and horns. The teeth are more pronounced, sticking way out like spikes or shards of glass, giving it the appearance of something from your nightmares ready to shred you to pieces.
