While Rocky and Willow were rowing 

Rocky: hey Willow do you think we should head back home 

Willow: no not until I can find my answers about the existence of mertrolls 

Rocky: I'm pretty sure they are not real and I the only way I will change my mind is if I see one

Then Fang appeared 

Fang: I know a place where you can get your answers from just follow me 

Then the kids rowed until they were by a cold icy lair where Ruby was expecting them 

Fang: children welcome the one and only Ruby

Ruby: hello children my name is Ruby and how may I help you 

Willow: I'm Willow and I was told that I could get answers about Mertrolls from you 

Rocky: why do you look like a octopus 🤨

Ruby: what do you kids want to eat unfortunately I only have cold food 

She shows them some sea food but some of it was twitching 

Both: um no thanks 

Willow: can you please tell me about this locket and why it has my name on it my parents won't tell me and my dad has this fear of the ocean and he doesn't understand 

Ruby: don't worry Willow your not the only one who has been misunderstood by a parent believe me I know how you feel and about your locket have you ever thought that it has your name on it because it's your destiny in it 

She then opens the locket showing the Mertroll Kingdom 

Ruby: and I think you know that deep down you weren't meant to be some lowly land troll

Rocky: um I'm standing right here 😠

Ruby: *ignores Rocky* what you are Willow is something far more enchanting 

Willow: a Mertroll

Rocky: I hate to burst your bubble but that's not possible besides last time I checked mertrolls don't exist 

Ruby: oh silly children anything is possible 

Willow: so you can turn me into a mertroll 🤩

Ruby: *shuts the locket* it's a piece of fish cake 

Rocky: but how 

Then Ruby looks through her stuff and grabs a purple potion 🧪

Fang: where did you get that 

Ruby: I actually made it myself  and one drop of this the you are a mertroll *thinking* the one thing I surpass my sister on since her attempt to turn a mertroll into a land troll got her banished and the next time she did it she got killed 

Willow: really 🤩

Rocky: I don't know Willow I don't trust her 

Willow: it will be fine Rocky you can just go back to your dads 

Ruby: now come on Willow your destiny awaits you 

Then she placed a drop of the potion on Willow's feet and she watched as her purple land troll legs were turned into a green mertroll tail 

Rocky: I don't believe this 🤯

Willow: I'm a mertroll 🤩

Rocky: I can't believe you are a mertroll Willow 😧

Then Willow immediately starts to swim around with her tail and was over the moon with her swimming skills as a mertroll 

Fang: hey wait a minute you could have changed me back to my normal size this whole time 😡

Ruby: patience Fang I'm still reeling her in 

Then Ruby dives into the water with Rocky remaining on the boat 

Willow: *hugs*  thank you so much Ruby 😄

Ruby: *fake cries*

Rocky: what's wrong you did something that's impossible 

Ruby: unfortunately my potion didn't have enough to make Willow's transformation a permanent thing 

Willow: please I don't want to go back to being a ordinary land troll is there a way for me to stay a mertroll 

Ruby: there is only one way but it's too dangerous 

Willow: what is it 

Ruby: I need my trident but was stolen from me years ago by the king of the sea 

Willow: maybe I can bring it back 

Ruby: you would do that for me 

Willow: yes I would do anything to stay a mertroll forever 

Ruby: ok this is a map to the mertroll kingdom 

Rocky: you mean that's real as well 

Ruby: yes now you kids can scatter 

Once the kids leave Willow to go get the trident and Rocky heading back home 

Fang: aren't you worried about the land troll boy knowing about this 

Ruby: relax Fang he is just a little land trolling and he won't get in the way of the plan
