Monster Life Farm Name Thread

From what I've noticed, you can't play with them when they're at 20/20, but you can still combine them as long as they aren't greyed out or have that "zzz" over their names.

I have 6 toys and 1 cat. There's another toy-type monster in the storage house. I got the cat from a C box.
Yeah, I guess there is a high chance of obtaining the same type of monster when using yours for combining.
I have a bunch of toy-type monsters (all rank B/B+) from using those for combining. I've also gotten the other type when combining, but I released them.

I spent around 20k waru combining my rank B+ with other Rank B and haven't gotten anything higher than a B+.
Also a side question... I know the effects die out in 30 days, but do the monsters go with it?

No they dont.
