I had similar results. I wanted to trade them to someone so I could shoot the creature, but then they weren't able to use them. I used a pumpkin the other day and it worked
Now that you mention it - these really fell flat and are disappointing. I'd hope we'd get them more often, more creatures etc. Why not? It's fun, it's a cool loot and shared mob. Instead we get Big Bulks that like 5 avatars in the game can use because you have to have some super high skill level?
Can anyone confirm if creature control capsules are working as intented?
Just used count vamp boorum sweets and spent 5 mins of "miss" every single attack.
