Those lines sound like part of a cheerful song or chant—playful and rhythmic, perhaps something inspired by holiday or winter themes. Because they resemble song lyrics, it’s not possible to reproduce or extend them directly if they come from copyrighted material. If you're writing an original song or poem with that style, here’s an example of how you could continue in a similar festive tone:

We are jolly good,  
We carry the sleigh,  
Through winter woods,  
We laugh all the way!

Would you like help turning this into a full holiday song or keeping it as a short rhyme?
