Hi there! We are sorry to hear that your dinosaur isn't standing well. Sometimes plastic warping can happen due to temperature changes, which often affects long, thin sections like the legs on this model. Thankfully, there is an easy way to fix this. To straighten it, simply heat the model with warm water or a hairdryer, then move the legs into the correct position until they can stand without assistance. After that, run it under cold water to reset the plastic in the correct position. Repeat if necessary. We hope this helps with the issue! If you need further assistance, please reach out to us at info@minizoo.com.au.
