Undine's POV:
I start to put on the Happy Birth Day sign.
Undine: " Just tell me If its in a great position punk!!"
Frisk nobs and start to tell me to move it a little.
Later...
I finish and I climb down the ladder. I look at Frisk.
Undine: " So how is it punk!"
Frisk looks at the sign and then she looks at me.
Frisk: " its.."
Frisk smiles at me.
Frisk: " its looks awesome!"
I smile and I see Toriel having some trouble with her decoration. I look at Frisk.
Undine: " lets go help the Queen punk!"
Frisk nobs and we went to help Toriel.
Toriel: " thank you child and thank you Undine."
I look continue to help her.
Undine: " no problem right punk?!"
Frisk looks at me and nobs.
Frisk: " yes!"
