Wow...that was...surprising, and good.
Nice effect on Spacerock Tower defences, TD

And Tram showing intelligence?
He is posturing, Father. Trying to unsettle us. Showing his contempt by doing the only thing he can, while he can.
This means Tram saw it coming, probably. And this also means that Tram is underestiminating Lord Hamster, even after all he heard from Charlie. Underestiminating your enemy is NEVER a good thing, and Tram is underestiminating the protagonist, which almost always results in defeat, especially if they say "what's the worst that could happen?"
And really, Wanda has a scary smile on her face
Oh also, Ossomer sayin "I am truly sorry, brother" with that look on his face seems like he's having pity on Tram and Jetstone.
Edit: Poor Duke, his arm melted

Edit2: This update showed us why the crap followed a strange route in mid-air. They aren't randomly crapping, they are targeting specific infantry, and those infantry are running. Dwagons have high enough attack to hit the infantry, even if they run, so their crap is homing, and follow the infantry.
