The mochi embraces you tightly and begins to life you into the air. Through the power of observation you can still see Katakuri down on the ground orchestrating everything with his own hands, like a conductor. The mochi around you takes the shape of a hounds head and it bites down on you. It then charges straight towards the floor, aiming to slam you into it. You know that if you don't get out it'll flatten you like a pancake. But with it being somehow liquid, solid, sticky, hard and heavy all at the same time you can't really get a hold of it. Unless...
"WHAT?!"
Katakuri watches in horror as you unhinge your jaw and take a big bite out of his mochi beast.
This works. Despite everything else mochi is still mochi. Quickly you shift into Turelim because that gives you the biggest mouth and go to town. Before hitting the ground about half of the dogs face is gone and you manage to jump to safety before impact. Katakuri doesn't seem too pleased and so he raises his hand. Your tell you to look up and you see that the roof is collapsing. Well, melting would be a more proper word. Katakuri brings down a sizable hill on your head and begins to press it down on you. However with great power comes great devour and you eat your way out with him being unable to do a thing about it. Popping out with a swollen gut you let out a burp and pat your belly.
"Neat trick! SLURP. And delicious!"
"Hmph. I'm glad you like it."
He almost sounds... pleased.
"Listen up pup. There is a whole other realm of power you haven't even tapped into yet. Under certain conditions a Devil Fruit can awaken to its true power and do things previously thought impossible!"
So that's how he's capable of doing all that stuff. He's not a Logia after all, just a very strong Paramecia. You lick your lips and not just because of the sweet rice cake sticking to them.
"Cool! Now... My turn!"
Katakuri flinches again. No doubt he's looking into the future now.
"How is that gonna help?"

He wants to see what you're trying to accomplish. Well. Better not disappoint him. You start focusing on your head, trying to concentrate all the potential of your devil fruit in there. With a quick burst your hair erupts, growing longer and thicker than before. It starts freely flowing behind you as you look down at Katakuri with a smirk.
"Silver Shift: Rahabim!"
Sensing danger Katakuri puts up his guard but it's too late. By the time he crossed his cube shaped arms you've gone past him and hit him in the chin with an uppercut. His head shoots up and his entire body follows it as arcs of lightning shoot out from the point you made contact. As he's flying high you jump after him and slam him back down with an axe kick.
