i must agree homemade inexpensive toys normally go down best!
I do have store bought toys simply because my dwarf does love them. Occasionally there is the one toy they detest - i know exactly wat you mean about the igloo ink, peggy detested when i offered instead of her usual bed and slept in her cardboard box
She now still prefers a cardboard box but i cut windows, doors and a chimney to make it look better XD
Porridge isn't a huge fan of shop bought toys, or if he is he gets bored quite quickly.
A good cardboard box, pringle tube and a wheel keeps him happy. Everything else is just extras for when his in the mood. Along with of course plenty of playtime.
