Her mother hears the girl talking and comes into the room. She spots a toad and kills it with a spoon.
From then on, the girl, who was strong and healthy, started losing her vitality. Soon, she becomes pale and thin. An owl starts howling at the house.
The girl dies a few days later.
II.
A girl sits on the wall and notices a toad coming out of the crack. She puts a blue neckerchief beside her.
The toad sees the neckerchief and returns to the crack. She returns with a little golden crown and puts it on the neckerchief. Then, she returns to the crack. The girl takes the crown.
When the toad notices the crown is missing, she gets back in the crack and never returns.
If the girl could wait, the toad would bring many more precious things from the crack.
III.
A toad croaks.
A girl hears croaking and calls the toad to show up.
The toad comes and the girl asks where is her little sister Little Red Stockings.
The toad says she didn't see her. Then, she asks if the girl saw her. After that, she makes a few more croaks.

As we can see, the tales are really short. The last one can be hardly even called a tale. The second one is also quite dry. The motif of the toad bearing gifts is already used in the first one, which is by far the most developed from the storytelling view.
Let's have a few words about the symbolism. There are three colors mentioned. While gold and red are pretty customary in Grimms' Fairy Tales, there is also the color blue (in the second tale). As you may or may not know, blue is traditionally used for authority and trust. The girl with a blue neckerchief establishes both. When she exploits trust by taking the crown, she loses authority as well. The toad won't come back.
The color red is mentioned in an interesting setting - the girl is asking for her little sister named Little Red Stockings, which reminds us of Little Red Cap.
And there is gold, of course, the color of crowns and precious stuff, but also the color of the Sun. Sun means light, warmth, and energy - all life on our planet gets energy directly or indirectly from the Sun.
Frogs and toads can symbolize different things, but they are, in general, good omens. There is an interesting article about the frog symbolism, but in short - frogs and toads are associated with fertility and good luck. Even modern scientists will agree. Seeing a frog means a clean environment.
Snakes (we mentioned some versions present snakes instead of toads), on the other hand, have a bit different symbolism. Still, they are in general connected with fertility. They are predators of rodents, who are harmful to people for many reasons. So, killing a snake would be bad luck.
