I have never seen a raging dragon 

 but I have seen a komodo dragon in London zoo

I have never ridden on a horse on a bike 

 but I have ridden a  bmx bike.

I have never seen a lion in the forest

but I have seen an emerald lizard.

I have never baked a cake with a fairy

But I have baked a chocolate cake.

I have never jumped in an erupting volcano

But I have jumped on a comfy couch.

I have never been to Portagaul to see a football match 

But I have seen a match in Engaland.

I have never been to tutamkamuns tomb 

But i have been to flaming hot Sauldi arabia .

I have never sunken into the alantian ocean 

But I have sunken into a cusion.
