Boots of Seed
These hobnailed boots appear as normal for their kind. However, with every step, each of the nails drives a seed into any hole they make. These magical seeds will grow into holly bushes at their normal rate of growth. Because of the density of the planting, these will function as 5' Walls of Thorns. The boots never run out of seed.
If the wearer is a Druid, this growth will occur overnight.
Animated Water Bottle - roams around watering things
Portable sundial - a mini sundial contained within a glass bauble which is always facing the right way to tell the time. Doesn't function if the sun cannot be seen.
