i can give you the bsl, if that's any use. they are really hard to describe so i hope they make sense!!!!
fixed: both hands with fingers and thumbs meeting at one point. bring two hands together at fingertips and twist each hand alternately at the wrist.
grapes: one hand holds an imaginary bunch of grapes by a stalk. the other hand follows the shape of imaginary bunch of grapes, coming to a point with fingertios touching thumb at the bottom.
strawberry: index finger of one hand points horizontally to second hand. second hand grasps the fingertip of pointing finger.
toast: both hands point downwards, one hand in front of the other (palms of hands facing signer) as though they are slices of bread going into a toaster
dummy: never used, but i assume it would be bunched fingertips to the mouth
goat: agian, i'm guessing it would be bunched fingertips pulling at imaginary goat beard from the chin
burger: imaginary big burger in hand held to mouth
bat: i'd do a sign like butterfly but facing the other way (ie butterfly, thumbs entwined hands like flapping wings, palms facing signer; bat = thumbs entwined, hands like flapping wings palms facing away from the signer)
rocket: fingertips of both hands meeting at a point, and blasting off!
robot: make like an 80's dancer!!!
dinosaur: sorry, i'd have to check that one
helicopter: index finger pointing up and moving round in circles
fox: hand pulls an imaginary snout shape from nose area, bringing fingertips to a point facing the nose.
oooft.... i'd be surprised if any of that makes ANY sense!!!!!
