Pupa for wasps.
It's probably from the white poplar.
The tree you're describing is likely the Lahash tree or African white mulberry (Morusalba). It produces clusters of small, fuzzy, white fruit with red dots, which are actually the flower remnants. These trees are often found in warmer climates and are known for their unique appearance and sweet fruit.
The tree adorned with green fuzzy balls is a mimosa tree.
White tree fungus can be identified by its powdery white appearance on the bark or branches of trees. It may also have a fuzzy or velvety texture. Additionally, white tree fungus can cause the affected areas to become discolored or decayed.

A mimosa tree?!
If it is a bush it could be a gooseberry.
A large fuzzy green caterpillar with yellow horns is a Imperial Moth caterpillar. These will go back into the tree if left alone.
It sounds like you are describing a honey locust tree (Gleditsia triacanthos). It is known for its large thorns and produces clusters of yellow, fuzzy fruit pods that contain sweet, edible pulp. Be cautious around the thorns, as they can be sharp and cause injury.
