Flying Wonder can take no Actions?

"I think some (many?) DMs would let you flavor a Bat familiar as a Flying Mechanical Wonder (since it has an established Stat Block and some similar features and is a CR-0 creature). This would let you share senses with the Flying Wonder as a Bonus Action."

Familiars ftom the Find Familiar spell for wizards can never attack. For warlocks, they can 

Familiars require a wizards bonus action to tell them to do something, often Help. Warlocks can swap on of their attacks to let the familiar attack.

An artificer homunculus servant has a force weapon that works in melee and to a 30ft range, and can fire without any action from the artificer.

Flying Wonders are magic items/constructs, so they dont have the restrictions that a familiar would (no attack)

So not sure a dm would quite so easily allow a player to reflavor one for the other. They are quite different and as a dm i might get confused about what the player is doing.
