I have four butter nut squash in our garden and we are planning to paint them and make them look like minions (from Despicable Me) for the Halloween. I don't know how it is going to turn out but let us see.
For the meantime, bumble bees love the flowers of the squash. They stayed in there the whole day and I am guessing that they also sleep inside the flower always see them inside buzzing around.
These would be fun to decorate with. I am not sure when to pick them but I am just going to leave them in the stem until they are old enough.
