Unless something that is not biodegradable was added to the tank (toy as you stated) everything will eventually breakdown. The question is do you have solid buildup in the tank? One way that can happen is the lack of water use, the black tank needs plenty of water all the time. Is it possible while dry camping your family conserved water while flushing?
If you are at a park, I would recommend you fill the tank fairly full with water. Let that sit 24 hours to hydrate any solids, then dump. It helps if you have a clear sewer attachment so you can see what runs out, and back flush with the one I linked to above.
If you still have a problem, add a cup of kitchen detergent (such as Dawn). Fill your tank just slightly. Then drive around in your RV, too much water you won’t get the agitation on the bottom of the tank. You want just enough water so when you slow down or accelerate you slosh. If the buildup is higher on the walls, you can increase the water volume and repeat. This won’t clean so much the lower section of the tank but will start to work the higher tank sides.
This should only be done after keeping the tank full to hydrate for 24 hours or the solids will be still firmly stuck to the walls. Some will say ice cubes but from my own experience and others testing it, the ice cubes do no better then pure water.
When driving I don’t have to go far. It’s more quick starts and stop, possibly some turning. You don’t need to do it at high speed, the key is agitation so abrupt changes will keep the water moving.
I like the Geo Method for maintenance. The basic idea is a water softener to keep things from sticking and soap for grime and smell. Start by adding two cap fulls of Calgon and 1/2 calgon cap of Dawn with water. Borax can be substituted for Calgon, it can be less effective and Borax should be dissolved in hot water before adding to the tank.
The way we do it is, dump leaving a park. Put the chemical in the tank with a bit of water before our next stop. When we arrive we fill the blank tank 1/3 or so and repeat.
