I can’t find appropriate synonym. In particular, I find it difficult to rephrase the following verbs: knock over, smash through and bounce through. Can you please help me??? Thank you.

1)Mr. Powell is counting the cost (synonym) after a teenage end-of-exam party in his home.
Last week Mr. Powell went on a weekend’s holiday to France. When he came back, he didn’t expect to find the disaster that happened.
2)He realized (found out) that his car windscreen had been smashed (I need a synonym: smashed, shattered, trashed, demolished, broken .. which are possible?), the roof of the car had been dented(I need a synonym: scratched, crushed, digged ) and the CD player had been damaged.
3)Further, a window had been broken and a clock had been smashed.
He said that the last time his daughter had had a party nothing had happened except that (?) a few bowls had been broken. He found out that the damage hadn’t been caused by his daughter but by the family cat, Pogo.
4)The car was therefore to blame for the cat-astrophe (this word is a play on words). Actually, Jessica decided to put the cat into (in) an upstairs bedroom because she feared he wouldn’t have liked it.
5) Pogo jumped onto a table near the window and knocked over (I need a synonym: ?) the clock.
6) The clock smashed through (rephrase) the window, fell onto the roof of the car and bounced through (rephrase) the windscreen. The cat then panicked (got frightened) and jumped off the table, onto the CD player.

1) An appropriate synonym for "counting the cost" in this context could be "assessing the damage" or "calculating the expenses".

2) Synonyms for "smashed" could be "shattered", "destroyed", or "crushed". For "dented", you can use "bent", "damaged", or "marred".

3) In place of "broken", you can use "shattered", "cracked", or "ruined". For "smashed", you could use "destroyed", "crushed", or "wrecked".

4) The phrase "cat-astrophe" is a play on words, combining "cat" and "catastrophe". It is a humorous way to describe the situation caused by the cat. The word "cat-astrophe" itself is the play on words.

5) A synonym for "knock over" could be "tip over", "upend", or "overturn".

6) Instead of "smashed through", you can rephrase it as "broke through", "shattered and passed through", or "crashed through". For "bounced through", you can use "rebounded through", "leaped through", or "jumped through".
