When Michelle takes Gilbert out of her bag, the way she holds him changes between shots.
Danny shows up at the camp saying "You left something behind". He proceeds to pull out Gilbert the rabbit even though Michelle was holding Gilbert when the girls went with Steve back to camp and they found the box empty with a hole chewed through it.
Michelle should've put the plate of s'mores on the coffee table instead of on the couch and Joey wouldn't have accidentally sat on them.
