I mean how does she afford it?! And what has she done with Archie? She has a great song (dododododo) but I think that's just a distraction from her freeloading.
Dr Ollie has the vets, Penny seems to be minted judging by her busy busy bees song where she lists her multiple income streams, PC Plum must be on a decent salary by now from Police Scotland and Miss Hoolie gets nursery wage.
Ava sings about loving to help her friends and just rewards herself with stickers from the nursery when she makes a good invention. (The solar panels)
She's going to need to get on dragons den with something decent or get a proper job before poor Archies money runs out.
