No they don't.Everyone gets a reward,even if you don't combact the monster.
And also:
Yoyo family:reward can be Yoyo buttermilk (70+hp) or YoYo Syrups (70+sp) and in this case you can choose
12 Mascots and Slame's Residence don't give you the chanche to choose,but you get some random reward (usually sp gum in 12 mascots,and fugu hot pot (in number of 10) in Slame's residence)
I didn't do the other instance yet,hope i explained these three clearly :)
