My 2yo likes to turn the hoover button on for me, then charge around the room with his walker "helping" to hoover. He likes helping to mop things with kitchen roll too.
Recently he has liked role playing with his plastic dinosaurs. Generally one of the dinosaurs gets up to something nefarious, for example knocking his friends off the table. The offending dinosaur them gets a good telling off.
Building tall towers with megabloks together, the knocking the towers down.
He likes it when I suddenly point to him and say "YOU!!" in a fake angry voice, which he then copies. Or " Slowly I turned, and saw.... NICHOLAS!!" followed by him being grabbed and kissed.
Monster box is a good one (and Halloween themed!). Make a monster out of a shoe box, with a big hole cut for the mouth. Then say "Monster's hungry, Monster wants to eat X!!". It can be anything lying about - plastic food toys, socks, a toy dinosaur... Monster then enthusiastically eats what the toddler bring, if it's right, or is outraged if the wrong thing is brought (our boy sometimes cheekily gets the "food" wrong on purpose, and goes up to the Monster giggling and eager for Monster to get offended ❤).
