Hi Jenny. Toads and frogs are my garden-friends. I love to see them, because they eat the slugs!
The difference is fairly easy: a frog jumps and a toad doesn't. A frog likes to be in
water. So probably this was a toad.
Mostly the toad just stays where it is, or otherwise it will walk/crawl away from you. Toads look a little ugly, and they are somewhat poisonous. But that poison is not very dangerous (only irritating), you can wash it away.
