Hedley Griffin 
Hot Cross Bunny [EPUB ebook] 

During a heat wave Harey, the hare-brained rabbit, and his friends are so hot, he goes into the pond to cool off and gets stuck in the mud. He then falls asleep and gets badly sun burnt. Running towards the house for a drink he rushes along the garden path and trips over, looks in the fridge for a drink, then finds a bottle of bleach which he drinks and burns his throat as well.
