Big Claw! Spoilers

I just collected Big Claw and my very first tap on him took place amongst a sea of characters who had just completed their tasks. Long story short, I was blinded by a blizzard of stacks of money AND blue (and yellow) XP icons. I don't know if Big Claw ran off at a high rate of speed or disappeared all together

If you got to see what happened, I'd like to know (I'd also like to know about the "pills" he's dropping)
