The Hydra
When the blue creature wedged its spear into the drawbridge, it swam to the far side of the castle. It bowed its face to a ledge. Upon opening its mouth, Dani and Jaivva jumped out unharmed.
"Sorry," said the creature, "This is the closest spot I could find".
"It's okay Nana," said Dani running ahead.
"It's so weird that I can talk to you like this," said Jaivva before running behind Dani.
Nana laughed right when a giant snake bit into her tentacled chin. It smashed her into the castle and ripped away.
Just as Nana was going to swing her giant blue arm a snake bit into it and another bit into her chest.
Seeing that it was a hydra, Nana kicked it away at its torso.
"Naaanaaa!" roared Mike from on top of one of the hydra's heads, "You better be ready for a fight"!
Dani fired a fully charged explosive at the hydra torso. One if its heads took the hit. It popped like a balloon. Blood rain over the three girls.
