CERAMICS!!
Especially around halloween, they have loads. Or in the garden section. Little dishes, tealight holders, small pots etc I have a little pot holder shaped like a hedgehog that I am super attached to that came from Poundland. You can get bags of peanuts, sometimes dried mealworms (intended for birds) etc as well.
They used to do bendy bridges and actual small animal stuff but I haven't seen any in any of my local poundlands in a long time
I still go in all the time to check (like yesterday) but I am consistently disappointed.
