Penguin Pickup
You are looking for a nano container with a penguin theme. Watch out, muggles about! Best done outside of school/commuting hours, although this can be a busy part of Benfleet at all hours.
Terrain etc. is wheelchair friendly but you will most likely need some assistance in reaching this one. Same goes for children, you will need an adult. Tweezers might be required although you shouldn't need them if it's been replaced carefully enough.
